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.
