Are DRL separate to side/dipped/main beam lights ?

Yes. My car has them (LED). It also has auto lights, which:
1) Come on when it's dark enough (FSVO dark)
2) Auto-dip


I was under the impression that it is mandatory for DRL to be separate
to any other light.

I can't see any point in switching DRL off. Anywhere.

Auto lights are pretty effective, for example through the tunnel on the
M4 round Newport. Signs say to use dipped headlamps but lots of people
don't. The auto lights snap on as you enter.

I didn't really want auto-dip and am happy with the LED lamps with
manual dip.

I'd like to think it could factor in any hills, up or down, surface

I'd agree that cruise generally works better on autos. My car, which
stays in 7th on the M40, is auto. And on real hills, it does change down
very nicely.

When I had a Saab turbo, I rarely needed to change down from 5th at any
speed from about 35/40 (and could usually go slower if I really wanted).
Would probably have been fairly happy to have cruise control in that.

Yes, I may not have described it correctly. The latest Volvo CC
certainly slows you down if the vehicle in front slows - maybe it then
maintains a speed dependent distance rather than a constant distance - I
not quite sure because I've never had the chance to try one. Whatever it
does, it sounds better than my current system which - when the vehicle
in front slows in a situation where changing lanes is not practical -
provides the option of either crashing into the back of the slowing
vehicle or dropping out of CC!

I used to, but now set it to the "speedo" speed (rather than real speed).
The 2mph acts as a buffer when you have undulating roads.

As far as I can tell I need to have something like a 1:12 dip before te
car overruns the cruise control at 30mph.

So I set em 2mph above, which is a true speed of around 30mph (according
to a friends satnav).

I wouldn't bother - it's rubbish. Or at least the version on my Discovery
was. It doesn't always actually dip, and when it does, it does it later
than I would manually do so, so you get flashed a lot anyway.

I was not convinced that it would do a better job than me - I try hard
to dip as soon as possible, even when the oncoming vehicle is still

Does it work?

Not really these days. Most larger cars tend to be autos. So
probably a cost thing rather than cultural.



More likely that the hydraulic gear change is so much more reliable
these days.


Decent autos - ie the epicyclic type - have been more reliable than
a clutch/manual gearbox combination for a pretty long time, in the
hands of an ordinary driver. Far more difficult to abuse. But cost
more and likely have an MPG penalty.



And how many drivers would actually notice ?

Mine does!

As does mine. I've never used the "handbrake" on my car in over four
years driving, except once to check that it would work for an emergency
stop.

No, it's CRAP. At least it is on our Honda CR-V (with manual transmission).
Whenever you stop on a slight slope, initially using the footbrake, then
apply the handbrake and release the footbrake, the car rolls a few inches
and then comes to an abrupt lurching stop. There seems to be no way to avoid
this; all you can do is release the footbrake gently so the car rolls slowly
and doesn't hit the end-stop so violently.

I've reported it to the Honda garage where we bought the car, and they have
checked it and found it to be "within spec". They say it's a side-effect of
having hill-start assist to prevent the car rolling back for people who
haven't mastered a hill start (which is a requirement of passing the driving
test!).

I'm very surprised that this amount of play in the handbrake mechanism is
regarded as acceptable and that Honda are happy to put their name and their
reputation on the line.

Every other car I've driven (over the past 35 years) has had no play in the
handbrake: if you come to a halt on the footbrake, apply the handbrake and
release the footbrake, the car stays put and doesn't move. I'm assuming that
the car is in neutral or the clutch is pressed so that the transmission
doesn't act as a brake or (if the engine is running) make the car lurch
forward when you let the clutch up.

Please explain that. To go from counting pulses to vehicle speed, an
interpretation has to be made somewhere. To do what you say, the
digital display would be in pulses per time period, which is
meaningless.

The accuracy of a 270 degree meter is only about 5% typically, if its
robust enough to be car usable. Add in voltage and temperature
fluctuations..

I am not sure if modern cars have speedo cables going to the speedo. Or
if they are simply milliammeters of some sort.

Quite obviously not really reflecting the minute variations in
temperature or oil pressure that happen in any engine all the time

When did cars stop using mechanical cables and eddy-current speedos? I'd
have thought quite a while ago. Analogue speedos tend to show a more
constant speed that early digital ones, though I imagine now that electronic
averaging is used so the digital display doesn't keep alternating between 29
and 30 (which is distracting).

Presumably either thermal or electronic averaging of signals to prevent
jitter on the needles.

No, it's a pain in the arse, at least as implemented in my C4. I don't
give a monkey's about whether the temperature I want is 22C or
whatever. When I get in the car, if I'm cold I want to get hot ASAP, so
I set temp to max. Once I'm warm enough, air at a somewhat lower temp
is what I want. So I turn the temp down from, say 27 to say 22. But
what actually happens is that instead of getting air at 22 I get air
*much* colder than that, because the car thinks I want the entire
ambient temp to get to 22 ASAP.

What I want is a simple slider or dial, such that I get air out of it
at a temp that exactly relates to the dial/slider position.

No reason why a well designed climate control can't have a
button which tells it to operate the way you want when getting
into the car cold and do it the way you want when you tell it to
stop doing that by unpressing that button when warm enough.

The climate control on my ancient BMW in auto mode starts with the fan
just idling on a cold start. Once the coolant gets warm enough, it ramps
up the fan speed to heat the cabin to the set temperature as quickly as
possible. As it approaches that temperature, it ramps down to a normal
quiet speed. And once at temperature, it opens the cold air vents to the
face, if that's what you want. If you select the AC, it does much the same
to cool the car. It works so well I very rarely touch it.

I was not convinced that it would do a better job than me - I try hard
to dip as soon as possible, even when the oncoming vehicle is still
round a corner. It might use full beam a touch more than I do.

You need to drive in the SE. You'll forget where the dipswitch is.

ECU driven. All sensors go into the ECU which 'interprets' them and
produces relevant signals.
