OT Toyota

If it's not the carpet that's causing Toyatas to speed up, then how
can replacing the gas pedal help?

I couldn't find the article I saw this in again. The problem is
moisture getting into the accelerator somehow. Symptoms of a possible
problem include the accelerator being harder to depress, not operating
smoothly, and or not returning to the upper position.

Well none of that is the pedal. They were still talking about the
actual pedal on Friday, the thing your foot rests on, right?

Then today Saturday they announced something but it's still about the
pedal, right?

The pedal is not just the pedal any more. It is an electronic device
with a footpad that tells the computer how fast you want to go and
some other servo motor opens and closes the throttle as needed.

In the past, metal rods or cables worked the throttle and a spring
pulled it closed. It is now a drive by wire system that should
failsafe to a closed mode, but evidently is not.

Drive by wire is still against the law. A cable runs from the pedal to
the throttle body.


Totally not true.


Brake by wire is also illegal.

To the best of my knowlege this may still be true. However, the early
Citroen D19 had a full pressure hydraulic braking system where a
"buuble" on the floor actuated a valve that controlled the brakes.
Also, electricall brake operation would be no less "positive" thanthe
current hydraulic system - which has NO mechanical linkage from the
foot to the wheel.

What the law DOES require is 2 totally independend brake actuating
systems - the service brake and the "parking" or "emergency" brake.
The 1949 VW did NOT technically pass this requirement as the same
cables operated all 4 wheels when the pedal was pushed OR the handle
pulled.
Steering by wire is
illegal too.
And also this. Full Servo steering IS used on construction equipment
and farm equipment.
