normal braking until you pump it too many times and runs out of the
vacuum. Don't pump them, apply pressure until you stop.

I told her that if her engine ever dies for whatever reason, that will

You loose the ASSIST. Means braking needs both feet and steering
needs some muscle. At speed the steering is not much of an issue,
while at low speeds it can be very difficult. Braking the
opposite.(sorta)


The good part about braking is you will have full power assisted braking
until you pump the pedal a couple times... so Don't Pump it!


Under hard acceleration, you may lack the vacuum assist as well.
Anyone who has driven a car with vacuum wipers knows what happens when
you are flooring the gas pedal. The wipers slow dramatically or stop.



Which is EXACTLY what was just said.

Vacuum assisted brakes have that large vacuum canister with a check
valve. A second or so idling and it has enough vacuum to work, and a
check valve so it works if your throttle is to the floor, or your engine
dies, it still has enough vacuum for a couple pumps. Try it with your
car in the driveway. Put it in park, turn off the engine, then pump the
brakes. You should get 1 to 3 good pumps before you feel in the pedal
that the vacuum assist is not working anymore.

But remember ONLY one to three pumps.

Two is a pretty good guess, and a VERY good reason NOT to pump the
brakes.

People forget they have a parking / "emergency" brakes? =A0What a crazy
world.
Not sure what your point is but if it's to suggest that the parking
brake could be used to stop a car while it's under near max power,
that won't work. They are intended for parking only, the brake pads
are smaller than the main pads,


Not true. The parking brake uses exactly the same pads that the service brake
uses, except (as noted) on only two wheels instead of all four.


When using the rear brakes with the brake pedal, they give about 20% of
the braking power. That is with vacuum assist! Using the parking brake
lever or pedal they provide even less braking power with no vacuum assist.



On many cars with read disk brakes the "parking" brake is a VERY small
drum brake inside the rear rotor and will have virtually NO effect on
slowing the car at speed, in gear or out.

The thing that really stood out to me was the statement by Toyota's president
that they're going to look into programming a brake override for the throttle.

I have only one question: WHY IN GOD'S NAME WAS THAT NOT THERE FROM THE
BEGINNING?

Because very many drivers will find the effect on driveability
something less than desireable?? And just how much authority do you
give the brakes over the throttle, and under what conditions, at what
road speed, and at what throttle position??

Maybe on YOUR car, but not on my Mercedes.


You make the mistake of generalizing on the basis of a too-small sample -- in
this case, a sample of one.

The parking brake pads are
completely seperate. I'm not sure what various other manufacturers
do. I'm sure others as you say do use the same pads.


Trust Mercedes to do something bizarre. Your car is the exception, I assure
you. *Every* vehicle I have ever owned used a cable to activate the same pair
of rear shoes or pads that were activated hydraulically by the service brake.
That list of vehicles includes three Dodges, a Plymouth, a Ford van, a
Fiat, a Chevy truck, a Dodge truck, two Mazdas, an Oldsmobile, two Buicks, two
Suburbans, two Saturns, and a Pontiac. _Every_single_one_ used exactly the
same pads or shoes for the parking brake as for the service brake.

And there is a list just as long that does not. Like most Volvos,
Corvette and any rear wheel disk GM and a few of the newer models of
just about every one of the brands you noted.

It is when they go for several miles (or even a mile) and then hit

!!!!

If I owned one of those Toyota vehicles affected, I would
install an auxiliary engine kill switch before I drove it again.

I would simply assure myself that I could tell the difference
between the brake and accelerator pedals. This is the same
****ing hysteria that struct audi ten years ago. The reports
vanished when audi installed an interlock so that the driver had
to have his boot on the brake pedal before putting the car in
gear.

Not even remotely the same thing.

And you were there in each and every case? People occasionally stomp
on the wrong pedal. It happens every week all the time. The only
thing different now is the media hysteria.

The only hysteria evident is yours.

The Toyotas, when they "run away" seem to do it while the driver is
just cruising along, sometimes already at highway speeds. Has nothing
to do with a foot hitting the gas pedal rather than the brake pedal.
In fact, part of the problem is that at 70-80 MPH with both feet
standing on the brakes, you can't stop the vehicle.

This has been widely reported.

The problem with Audis would happen when the car was being moved from
a standing position because of the size and position of the pedals
making it easy to push the wrong one without realizing it.

Also widely reported.- Hide quoted text -

"In fact, part of the problem is that at 70-80 MPH with both feet

I'm admittingy tossing out "partial information" here, since I can't
cite the source.

The other I heard a gentleman who was being interviewed on the radio -
who I believe was a spokesman from some Auto Safety organization - who
stated:

"In any passenger vehicle, even the weakest set of brakes is more
powerful than the strongest engine. There is no reason that a driver
should not be able to stop a Toyota when it exhibits the run-away
problem. The key is to not panic, apply the brakes, shift into neutral
and pull to the side of the road."

Sounds easy enough. ;-)

that quote doesn't imply the brakes will stop the car without being in
neutral. the brakes won't stop the car if, in fact, it is in gear and
accelerating (or at least once the breaks start slipping due to
overheating), it won't.

"that quote doesn't imply the brakes will stop the car without
being in neutral."

I'm not arguing whether the brakes will stop the car or not, but I
will argue that that is most certainly what the quote implies.

"In any passenger vehicle, even the weakest set of brakes is more
powerful than the strongest engine."

If indeed the brakes are stronger than the engine, then they will stop
the car even when it is in gear.

What would be the point of going on the radio and stating that "Any
brake system will stop a car that is in neutral."? That's pretty
obvious.

I can certainly see that as written in my post, you could take the
quote to mean the car must be in neutral. However, had you heard the
speaker speaking, with the inflections and pauses where they were, you
could easily tell that he was making 2 distinct points:

1 - The brakes are strong enough to overcome the most power engine.
2 - Here's the process to follow if you have a stuck accelerator.

Number 2 doesn't make Number 1 false.



All you need to do is look at accelleration figures in comparison to
stopping distance figures. A car takes X number of feet to accellerate
from a stop to 100 KPH. The stopping distance is generally something
in the neighbourhood of X/4 feet, meaning the brakes are dissipating
roughly 4 times the power the engine is producing.


It's not just Brakes vs Engine, though. See also mass, momentum,
inertia and gravity for additional information.

Unless of course, you are driving a weightless car.


The inertia affects accelleration EXACTLY the same as it affects
braking. Going down hill when stopping vs uphill acclellerating, or
vice versa, would skew the results somewhat.

While there may be some sort of unsolved interface problem that causes
an unexpected acceleration one does wonder how many genuine instances
there are? And maybe how many litigiuos one!

There may be also be something to the allegation 'Here's chance to
take a bite out a none North American auto producer'.

But how many 'incidents' are due to driver error or insufficient
competency in dealing with something unusual.

Every driver SHOULD, although one doubts whether many do, know what to
do if/when their vehicle acts in an unexpected manner.

For example when we started towing a trailer with a 1976 Chev. Impala
we reviewed what could happen if, for example we lost the car's power
assisted hydraulic brakes (no dual braking then!) and/or the engine
stopped and we had no power assisted brakes or steering. With engine
off we then practiced bringing the whole rig to a stop by using the
foot operated parking brake. Never had to do it for real but knew we
could and with the family and all gear on board.

In another instance we had a V.W diesel 'take off' (running on it's
own crankcase fumes on a warm day). Having read about the probable
cause we depressed the clutch, disconnecting the engine which started
to race uncontrollably; pulled into side of the road, stopped, and
then stalled the engine, hoping not break anything! It stopped and
when the engine had cooled bit we drove to the dealer.

Many years before, in 1953/4 we had a wheel break off the rear axle of
a 1926 Daimler! But again somehow we knew which way to turn the wheels
and brake (manual rod brakes no power assist at all) to bring the
vehicle to a halt without turning over.

Included in the above axiom of "Think about what COULD happen and
rehearse what to do about it", is that all members of this family
(except one) prefer manual vehicles and state a preference for a
proper hand brake lever located centre console. Which also means that
in certain emergency situations the front seat passenger could also
operate the handbrake!


How do you explain the fact that over the last 5 years or so Toyota
has a rate of these incidents happening that is 2X or 3X the rate of
other car manufacturers? If it was just people doing something
wrong, the rates should be about the same. They are not. I saw a
chart comparing them and GM was low, at like 1/3 the number of
Totyota. And Toyota was similar to other manufacturers before they
moved to the new fly by wire system. Which is not to say that proves
it's an electronic problem, it could be something mechanical in the
design too, but it does tend to support that it's an electronic
problem.



The reported pedal friction problem would account for the increase.

And what about GM's recall for defective power steering????
Not the first one either. If not recalled, they should have been back
in 1979-1989?? when steering racks on GMs were getting stiff and
causing very severe "pull" to either left or right when the racks wore
out at anywhere from about 10,000 miles on up.
Different system, and different problem today - but like many susect
with Toyota, electronic in nature.

Wheres the bigg hullabaloo now?????

I'd love to see a physics class [or Mythbusters] take out the words
like "a car" and "x number" and "generally in the neighborhood" and
"roughly". throw in a few things like inertia and the difference
in a drive train and brake pads. . . and find out why none of the
reports that I've heard have said "The engine was at full throttle, I
was going 50 miles an hour and was able to get the car stopped with my
brakes."

Even the guy who drove to the dealership with a full throttle engine
who had the presence of mind to go to neutral, brake, go back in gear,
accelerate. . . then back to neutral for control said his brakes would
not slow the car while it was in full throttle position.

Looking for more proof for *my* thoughts- I found some middle ground
in actual research by Car & Driver-
http://www.caranddriver.com/features...tion-tech_dept

In a nutshell-
"Certainly the most natural reaction to a stuck-throttle emergency is
to stomp on the brake pedal, possibly with both feet. . . . brakes
by and large can still overpower and rein in an engine roaring under
full throttle. With the Camrys throttle pinned while going 70 mph,
the brakes easily overcame all 268 horsepower straining against them
and stopped the car in 190 feet€”thats . . . just 16 feet longer
than with the Camrys throttle closed. From 100 mph, the
stopping-distance differential was 88 feet€” . . . We also tried one
go-for-broke run at 120 mph, and, even then, the car quickly
decelerated to about 10 mph before the brakes got excessively hot and
the car refused to decelerate any further."

Maybe by the time you got to 10MPH you'd have the presence of mind to
put it in neutral-

Don't know why they didn't try a Lexus. Would have loved to see what
happened if you first tried the brakes-- then applied full power.
Seems like that would have been human nature.


HOWEVER - the brakes must be applied HARD - and STEADY - NOT PUMPED -
to stop the vehicle as quickly as possible. Lighter braking will give
the brakes too much time to heat up and fade - and pumping at WOT
looses your vacuum boot VERY QUICKLY.


If you are going slow enough, and your brakes are good enough, I
agree, you have a chance by mash 'em and hold 'em. Problem is-
it isn't a perfect world. In the Calif crash, the car was a loaner
whose brakes were already compromised. [still- it looks like
shifting into neutral should have saved the day. but we don't *know*
that they didn't try that.]


Oh, we KNOW that, because in neutral a car will NOT accellerate unless
going down a very steep hill or falling off a cliff.

Audi & a couple other manufacturers have a shut off on their
drive-by-wire vehicles, so hitting the brakes kills the throttle. I
hate the idea of software on throttles, brakes, or steering-- but that
one seems like common sense. OTOH- if this is a computer problem,
what's to say that would work anyway.

"Should" ain't "doesn't" no matter what it is; if it's mechanical it can

Not reacting properly when there apparently was quite a lot of time
(evidenced by 911 call in the CA incident) makes the participant an
(albeit unwilling) accomplice in the result of a failure (granted) not
of their doing initially.


Unless there was a complete failure of the ignition system _and_
transmission shifter as well as the accelerator, then yes, there's no
doubt there was operator error involved as well as the mechanical failure.


Nobody's blamed those involved for the initiating event; only questioned
the outcome as being inevitable.


The counter example cited is too dissimilar to be of any import -- in
that case the remedy is to take some unusual precaution a priori (of
course, if one is proposing a walk in a particularly unsavory area after
dark if just might not be so unusual to either choose another
entertainment venue or take the precautions); in the case under
discussion it's the lack of an appropriate response to the event after
it has occurred when there is ample opportunity to take corrective
action (and afaik there's no data that says such actions aren't possible).


So, I'll disagree with the assertion that there's no culpability in
severity of outcome independent of the driver in the incidents until and
unless it's shown that the remedial actions were unavailable.

You have to hold the button for something like three seconds. Â*That sounds

Apply brakes, shift into neutral.

No more acceleration.


Do you know for sure how the shift mechanism works on all these cars?
The throttle is fly by wire, what makes you so sure there isn't
something similar for the tranny that could block it from being moved
into certain positions under certain conditions? That even seems
desirable, does it not? Like preventing it from being moved into
park while it's moving?


How about like " I tried it on a Lexus ES300 and you can put it in
neutral any time you like, and when in neutral the car slows down, and
when floored in neutral the tachometer jumps between 3000 and 4500
rpm"

As for the 3 seconds to shut the engine off via the starting button on
the Lexus, that is indeed the case. And it's worse than that it
could take 3 seconds while roaring down the highway. Who would know
that it takes 3 seconds and hold the button in for that long?
Apparently it takes 3 secs while the car is moving, which is not the
normal shut-down sequence you would experience everyday. In fact,
you'd most likely only experience it when something was seriously
wrong. And then it would seem more likely many people would continue
to push the button again and again instead of just holding it in. To
top it off, the Lexus was a rental, so the driver had no familiarity
with it.

I'm quite amazed at how people want to just attribute this to driver
stupidity. In the famous Lexus case the driver was an experienced CA
highway patrol officer who had taken special driving training as part
of his job. I'd be pretty amazed if he didn't try to put the car in
neutral.

It's common to have failures that are not readily repeatable by service
techs. You can't fix when you cannot diagnose,because the reported problem
did not occur when checking it out.


and isn't the operator responsible for learning about the engine shut-off
procedure from the Operators Manual? Even if it's a loaner?


The operator should have known there was a problem, diagnosed it and
fixed it properly before leaving the dealership. He must have been

All you need to do is look at accelleration figures in comparison to
stopping distance figures. A car takes X number of feet to accellerate
from a stop to 100 KPH. The stopping distance is generally something
in the neighbourhood of X/4 feet, meaning the brakes are dissipating
roughly 4 times the power the engine is producing.


I'd love to see a physics class [or Mythbusters] take out the words
like "a car" and "x number" and "generally in the neighborhood" and
"roughly". Â* Â* throw in a few things like inertia and the difference
in a drive train and brake pads. . . Â*and find out why none of the
reports that I've heard have said "The engine was at full throttle, I
was going 50 miles an hour and was able to get the car stopped with my
brakes."

Even the guy who drove to the dealership with a full throttle engine
who had the presence of mind to go to neutral, brake, go back in gear,
accelerate. . . then back to neutral for control said his brakes would
not slow the car while it was in full throttle position.

Looking for more proof for *my* thoughts- I found some middle ground
in actual research by Car & Driver-http://www.caranddriver.com/features/09q4/how_to_deal_with_unintended...

In a nutshell-
"Certainly the most natural reaction to a stuck-throttle emergency is
to stomp on the brake pedal, possibly with both feet. Â*. . . Â*brakes
by and large can still overpower and rein in an engine roaring under
full throttle. With the Camry s throttle pinned while going 70 mph,
the brakes easily overcame all 268 horsepower straining against them
and stopped the car in 190 feet that s Â*. . . Â*just 16 feet longer
than with the Camry s throttle closed. From 100 mph, the
stopping-distance differential was 88 feet . . . Â*We also tried one
go-for-broke run at 120 mph, and, even then, the car quickly
decelerated to about 10 mph before the brakes got excessively hot and
the car refused to decelerate any further."

Maybe by the time you got to 10MPH you'd have the presence of mind to
put it in neutral- Â*

Don't know why they didn't try a Lexus. Â* Would have loved to see what
happened if you first tried the brakes-- then applied full power.
Seems like that would have been human nature. Â* Â*



HOWEVER - the brakes must be applied HARD - and STEADY - NOT PUMPED -
to stop the vehicle as quickly as possible. Lighter braking will give
the brakes too much time to heat up and fade - and pumping at WOT
looses your vacuum boot VERY QUICKLY.


If you are going slow enough, and your brakes are good enough, I
agree, you have a chance by mash 'em and hold 'em. Â*



Going slow enough? According to your own source, which I think is an
excellent one, even at 120MPH the brakes were capable of slowing the
car to 10mph. At that point, if all else failed you could stear the
car off the road into a guardrail, ditch, or some similar roadside
place to bring it to an end.


Â* Â* Problem is-
it isn't a perfect world. Â* Â*In the Calif crash, the car was a loaner
whose brakes were Â*already compromised. Â*


How were the brakes compromised?





[still- it looks like
shifting into neutral should have saved the day. Â*but we don't *know*
that they didn't try that.]


How do you know that they didn't try that? With a CA highlway patrol
officer that was trained in police driving techniques and surely isn't
an idiot driving, I would strongly suspect that they would have tried
it.




Audi & a couple other manufacturers have a shut off on their
drive-by-wire vehicles, so hitting the brakes kills the throttle. I
hate the idea of software on throttles, brakes, or steering-- but that
one seems like common sense. Â* Â* OTOH- if this is a computer problem,
what's to say that would work anyway.

Jim


It would work if the circuit that cuts off the throttle when breaking
is independent of the computer.



Very simple - disconnect power to injectors - that will stop the
accelleration. But you need a "computer" of some sort to tell that
relay when to actuate, according to throttle, speed, and brake inputs.

Because very many drivers will find the effect on driveability
something less than desireable?? And just how much authority do you

When I was a teenager, I was driving the family '67 Chrysler aircraft
carrier when the throttle return spring broke on the big 383 V8. I cut
the ignition, pulled over to the side of the road, opened the hood,
fixed it with a pair of pliers and went on my way. If it had happened
to my mother or one of my sisters, the outcome may have been different.
I'm not picking on women but my aunt was driving down a highway when
she saw a wrong way driver coming straight at her, she let go of the
wheel, covered her face and started screaming. My male cousin grabbed
the wheel and steered the car to safety. Perhaps drivers education
classes should take a hint from aircraft pilot training and train for
the inevitable odd mechanical or human brain failure.

you hit black ice

Okay, how many of the items above do YOU practice dealing with on a

And by practice, I mean, replicate the situation and drive out of it.

Better than uncontrolled acceleration, undoubtedly.

Unless they're fully hydraulic steering (of which I know of no autos; do

steering. Same w/ the brakes, it's only the power assist.

The actual recommendation is to shift to neutral and let it over-rev;
what possibility/likelihood of blowing an engine is I've not firm
estimate but if that happens you're in same boat anyway...

Probability of blowing the engine is much less than 2% - the compiuter
shuts off fuel at about 4500 RPM in neutral.

Unless of course the runaway condition is being caused by a fault in
the computer!

Would need to be a compound fault, as the rev limiter has no
connection to the throttle. It shuts off injectors.
SO - even if the "unintended accelleration" problem IS a computer
glitch, it would still not blow up if put in neutral.......


If the computer is malfunctioning, then I think you can allow for the
possiblity that it may not do what you expect on many fronts. We don't
know the nature of what is causing the fault. Is it an unreliable
oscillator? A bad ground? Leaky capacitor? Power fluctuations?
Electrical noise? Any of those things could have widepread
repercussions in the computer.


Anything that stops the clock would, by necessity, stop the engine
because the clock is required to fire the injectors and time the
spark. Absolutely IMPOSSIBLE for the engine to run if the oscillator
(clock) of the ECU was to fail.
Pretty much the same with a bad ground - as the injectors are ALL
powered externally and grounded through the ECU. Also, all the sensors
go to higher voltage as the input increases. A ground (Other than the
wired signal ground for each 3 wire resistance type sensor) is not
required on the majority of sensors, and if that ground went bad the
reference voltage would go out of spec, throwing a code or the sensor
would be detected as an open circuit (also an out of range value),
throwing a different code.
About the only thing external that could be causing an accelleration
problem would be digital noise entering the system as RFI that just
happened to be exactly the right frequency and amplitude , at exactly
the right place, to fool the computer into thinking it was a
legitimate signal.


Nice try, but it's obvious you don't have an advanced degree in
computer science.

Loose it, or it becomes more difficult? That would be a shame if I
couldn't steer or brake my car because I ran out of gasoline. Are there
any vehicles like that?

When I taught my niece to drive, in a large empty parking lot, at about
35mph I told her I was turning off the engine. Then I told her to make
a left hand turn. She's a tiny little thing but she struggled and it
did turn. As far as the brakes, if it's vacuum assisted you still have
normal braking until you pump it too many times and runs out of the
vacuum. Don't pump them, apply pressure until you stop.

I told her that if her engine ever dies for whatever reason, that will
be the result, so be ready for it.
You loose the ASSIST. Means braking needs both feet and steering
needs some muscle. At speed the steering is not much of an issue,
while at low speeds it can be very difficult. Braking the
opposite.(sorta)

The good part about braking is you will have full power assisted braking
until you pump the pedal a couple times... so Don't Pump it!


Under hard acceleration, you may lack the vacuum assist as well.
Anyone who has driven a car with vacuum wipers knows what happens when
you are flooring the gas pedal. The wipers slow dramatically or stop.



Which is EXACTLY what was just said.


Really? Who other than me said that under heavy acceleration, engine
vacuum is reduced?

I'll give you a hint: NOBODY

If I owned one of those Toyota vehicles affected, I would
install an auxiliary engine kill switch before I drove it again.

I would simply assure myself that I could tell the difference
between the brake and accelerator pedals. This is the same
****ing hysteria that struct audi ten years ago. The reports
vanished when audi installed an interlock so that the driver had
to have his boot on the brake pedal before putting the car in
gear.

Not even remotely the same thing.

And you were there in each and every case? People occasionally stomp
on the wrong pedal. It happens every week all the time. The only
thing different now is the media hysteria.

The only hysteria evident is yours.

The Toyotas, when they "run away" seem to do it while the driver is
just cruising along, sometimes already at highway speeds. Has nothing
to do with a foot hitting the gas pedal rather than the brake pedal.
In fact, part of the problem is that at 70-80 MPH with both feet
standing on the brakes, you can't stop the vehicle.

This has been widely reported.

The problem with Audis would happen when the car was being moved from
a standing position because of the size and position of the pedals
making it easy to push the wrong one without realizing it.

Also widely reported.- Hide quoted text -

"In fact, part of the problem is that at 70-80 MPH with both feet

I'm admittingy tossing out "partial information" here, since I can't
cite the source.

The other I heard a gentleman who was being interviewed on the radio -
who I believe was a spokesman from some Auto Safety organization - who
stated:

"In any passenger vehicle, even the weakest set of brakes is more
powerful than the strongest engine. There is no reason that a driver
should not be able to stop a Toyota when it exhibits the run-away
problem. The key is to not panic, apply the brakes, shift into neutral
and pull to the side of the road."

Sounds easy enough. ;-)

that quote doesn't imply the brakes will stop the car without being in
neutral. the brakes won't stop the car if, in fact, it is in gear and
accelerating (or at least once the breaks start slipping due to
overheating), it won't.

"that quote doesn't imply the brakes will stop the car without
being in neutral."

I'm not arguing whether the brakes will stop the car or not, but I
will argue that that is most certainly what the quote implies.

"In any passenger vehicle, even the weakest set of brakes is more
powerful than the strongest engine."

If indeed the brakes are stronger than the engine, then they will stop
the car even when it is in gear.

What would be the point of going on the radio and stating that "Any
brake system will stop a car that is in neutral."? That's pretty
obvious.

I can certainly see that as written in my post, you could take the
quote to mean the car must be in neutral. However, had you heard the
speaker speaking, with the inflections and pauses where they were, you
could easily tell that he was making 2 distinct points:

1 - The brakes are strong enough to overcome the most power engine.
2 - Here's the process to follow if you have a stuck accelerator.

Number 2 doesn't make Number 1 false.


All you need to do is look at accelleration figures in comparison to
stopping distance figures. A car takes X number of feet to accellerate
from a stop to 100 KPH. The stopping distance is generally something
in the neighbourhood of X/4 feet, meaning the brakes are dissipating
roughly 4 times the power the engine is producing.


It's not just Brakes vs Engine, though. See also mass, momentum,
inertia and gravity for additional information.

Unless of course, you are driving a weightless car.


The inertia affects accelleration EXACTLY the same as it affects
braking. Going down hill when stopping vs uphill acclellerating, or
vice versa, would skew the results somewhat.

"Should" ain't "doesn't" no matter what it is; if it's mechanical it can
fail.


Not reacting properly when there apparently was quite a lot of time
(evidenced by 911 call in the CA incident) makes the participant an
(albeit unwilling) accomplice in the result of a failure (granted) not
of their doing initially.


Unless there was a complete failure of the ignition system _and_
transmission shifter as well as the accelerator, then yes, there's no
doubt there was operator error involved as well as the mechanical failure.


Nobody's blamed those involved for the initiating event; only questioned
the outcome as being inevitable.


The counter example cited is too dissimilar to be of any import -- in
that case the remedy is to take some unusual precaution a priori (of
course, if one is proposing a walk in a particularly unsavory area after
dark if just might not be so unusual to either choose another
entertainment venue or take the precautions); in the case under
discussion it's the lack of an appropriate response to the event after
it has occurred when there is ample opportunity to take corrective
action (and afaik there's no data that says such actions aren't possible).


So, I'll disagree with the assertion that there's no culpability in
severity of outcome independent of the driver in the incidents until and
unless it's shown that the remedial actions were unavailable.

After these incidents, cars may go back to that.


at the very least it should be mandatory to have the panic shutoff

BTDT, very similar experience about 7-8 years ago with my Suburban at +/-

shut the engine off, replaced the spring, used a twist-tie as a temporary

Not true, My Sonata has rear disc brakes, but the parking brake has shoes

Depends on the vehicle. In my experience, the overwhelming majority use the

The thing that really stood out to me was the statement by Toyota's president
that they're going to look into programming a brake override for the throttle.

I have only one question: WHY IN GOD'S NAME WAS THAT NOT THERE FROM THE
BEGINNING?

Because very many drivers will find the effect on driveability
something less than desireable??


Only that small number of fools who make a habit of using the brakes and
throttle simultaneously.

And just how much authority do you
give the brakes over the throttle, and under what conditions, at what
road speed, and at what throttle position??


Absolute authority at any speed over, say, 5mph. Obviously.

And how many of these procedures does any reasonable person do with a
RENTAL car, The Lexus death car driven by the CA highway patrol
officer was a rental car. Is it reasonable for that driver to know
that when the car is traveling the procedure for turning off the
ignition is very different from turning it off when the car is
parked? It takes pushing in the dash start button a full, continuous
3 seconds. Would you do that or would you do what many people might
do, push it in for a second or two, then try again? Do you read
the owners manual before driving off? Tell the truth now. In fact,
most of the rental cars I've had didn't even have the owner;s manual
in them. Even if you read it in the manual in your own car, would you
remember it 3, 5 years later in the middle of an emergency.

I quite amazed at the superiority complex some folks have here. You
assume you would do so much better at handling this than a trained CA
highway patrol officer in a car with 3 other people who also had
considerable time to come up with ideas on how to stop the car. I
think in view of not knowing all the facts and with so many of these
unexplained accidents, SA and I are not so willing to jump to
conclusions. And I also think no matter what happened, from what we
know a lot of the blame falls on Toyota because it's clear:

A - In the Lexus at least, it takes a continuous 3 sec push to turn
off the ignition of the car while moving. That seems excessively
long.

B - Toytota, unlike other manufacturers, chose to not have an
interlock that disengages the throttle when brakes are applied

C - They knew about these increasing incidents for a long time and
didn't do enough.

It's amazing how you can rush to judgement. The driver wasn't some
kid, a guy half drunk or a partly senile old man. It was a CA
highway patrol officer trained in advanced driving techniques. He
had THREE other people in the car that could also come up with ideas
how to stop the car. Have you analyzed the car and know how it
operates? Already we know a good reason why they would not have been
able to shut off the Lexus. It takes a full 3 second push on the
start button. How long do you think 3 secs is going to seem to you
when you're in a car in traffic going 90mph and accelerating? Would
you be so knowledgable and rational under those conditions? Or would
you wind up dead and being called stupid?

As for the rest of the possible ways of stopping the car, without
carefully reviewing the design of the car and the crashed car, it's
premature to rush to judgement.

Right

While I *might* not want to be able to put a tranny in park while it's

for the very reason this "snow on the roof" thread has continued for
so long.

If my throttle got stuck, whether by a floor mat, an electronic fault,
a driver having a heart attack or a car jacker with a death wish, I'd
be really ****ed if I couldn't pop it into neutral in an attempt to
keep myself alive.



Yes, but you missed my whole point. You acknowledged that it's
desirable to have some kind of interlock to keep the car from being
shifted into at least Park while it's moving. OK, so I implement
that system via an interlock system consisting of a solenoid driven by
the computer. That's right, the same computer that is malfunctioning
and has the throttle pegged. How do you know the computer isn't
stuck in some erroneous program loop or state and isn't responding to
ANY commands? Until someone has a definitive independent study of
what happened in a lot of these cases, I'm not going to rush to
judgement against the drivers.
