It seems to me that the cruise control doesn't know how fast you are
going but it does know how fast the drive wheels are spinning and if
you lose traction, they will start to spin faster, and the cruise will
let off the accelerator umtil the tires slow down.
With almost no traction, as in hydroplaning, (which the cruise control
will see as equivalent to going down a steep hill, where gravity
cancels out drag) won't the engine speed have to drop dramatically,
perhaps all the way to idling? And it won't go up again until the car
regains traction.

>WET OR ICY,
I will admit, that iirc, I don't use cruise on wet or icy pavement,
but that is because I want full control of the car and think I can
take my foot off the accelerator quicker than the cruise (which might
not even be true. Which do you think is faster in decelerating, me or
the cruise?), but I still don't think the cruise will make the car
accelerate.

Anyone know anything about this car. The post** seems like a hoax,
but hoax writers often put in stuff like this to make it sound real.
**Well, actually the email I got had a lot of stuff in it, totally
unrelated, nor related to cars or safety. And from a good guy who got
it from a good guy, from a very good guy. I think someone was
suckered.

I found one page that says the car has wiper warmers, but didn't say
anything about wipers and cruise. (although it would be harder to
notice)

Correct in most every case.

I use it all the time in light rain and when dry, but far less than the mile
you state. Both my cars have traction control or stability control and the
cruise control gets knocked off at the slightest hint of wheel slip. Not
every car has that. ESC is really nifty. I was playing in the snow in our
parking lot at work and it gives amazing control in slippery conditions.

at least my old car the cruise control speed was monitored by a
gearbox in the speedmoter cable. i know because the gearbox failed and
my speedometer went to zero

Because I'm the world's best non-professional driver, the following doesn't
apply to me: I'm convinced that on wide open highways with very little
traffic, cruise control lulls people into a mental state similar to watching
late night television when you know you really should just go to bed. So,
people think they're being good drivers, but in fact, they're not.

Hi,
They are motor vehicle operators not drivers. Driver is the one who is
in control of his/her vehicle at all times regardless of road and
weather condition.
