I used my last car for 18 years, and very, very rarely used the
cruise
control. This car, owned for a year, I haven't bothered finding out
how the cruise control works.

I'm on my fourth car with cruise and each I used extensively. No
point
in having a driving aid fitted, if you don't use it. I took time to
learn how all the gadgets on my car work.

The satnav, the auto wipers, the auto seat, the reverse sensors, auto
climate and so on. Even how it constantly checks the caravan's lights
are all working and puts a brake light on half power as a substitute
when a tail bulb fails.

Auto climate is a pain in the arse.

No, it is great. I can just leave it to get on with it. I dislike
manual
control, I would be constantly having to retrim it as the outdoor
ambient
changed.

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.



Why would you want a system to mimic idiotic behaviour?

For those who want it to operate like that.

Climate control left to its own devices does *exactly* what Tim is trying
to achieve without interference.

No it does not when the person wants the car much
hotter than normal when they have got very cold
outside the car, want to be warmed up as quickly
as possible when they get into the car, and then
automatically return to normal temp once the
individual has been quickly warmed up.

It works to get the cabin to the preset temp as quickly as possible.

But he doesnt want the preset temperature initially,
he wants much warmer to warm himself up quickly.

If the engine isn't hot enough no amount
of fiddling will get it to heat up faster.

But when the engine is hot enough, it can do what he wants.
