Is this true?

I wish all cars would automatically turn on the headlights when the wipers are on. So many gray and white cars are hard to see. And the drivers are clueless. I flash them all the time with my brights.

And then the drivers flip you off because they have no clue and think you're flashing them because you are just a rude, nasty person.

Worst case, they cancel each out -- which might still be bad. But in all likelyhood the cruise control is cut if VDC kicks in.

My Mazda 3 has neither stability control nor traction control so I definitely keep the cruise control off when it rains. In my Z, I don't think I've ever used it rain or shine ...

I don't know whether it's true or not, but I just can't see why you'd want to cede throttle control to your vehicle in potentially slick conditions. If anything, that's probably where I want it the most.

I've thought of that myself, since it is technically the law where I drive, but I can see practical applications for "wipers on, lights off" when the car is stopped. Maybe that's the answer, if the car is moving more that, say, 40mph with the wipers on, the lights come on automatically.

I quite agree. As I mentioned I never use my cruise control at all. I was just pointing out that modern electronic nannies have likely made the conventional wisdom that cruise control in rain can cause unintended acceleration not applicable to cars that have these traction control devices.

I'm not denying it is still best to maintain full control of your vehicle in such conditions

I wonder... I bet the top of the line ones do. Like, I bet a 2012 Merc S Class probably would. I wonder if it trickles down to a 30-40k sports car, or even indeed a 20k grocery getter.

It would be interesting to learn.

I think all of them should have such capability, but you and I are in agreement, I don't use CC in the wet stuff.

I think the high-end nannies know how to override human input -- steering throttle, etc. It is likely quite a bit easier to simply overrule the cruise control which happens merely by braking.
