Someone wrote me:
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.
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)
