No cruise control in the rain?

I was always told when learning to drive that you shouldn’t use cruise control when it’s raining. I never have but why can’t we?

It’s mainly old thinking. It was bad on early analog systems because the system couldn’t control the vehicle in dangerous situations and could unpredictably accelerate causing the driver to lose control.

With newer abs systems (late 80’s and newer) and traction controls the car will usually disable cruise control if it sees something dangerous. This can also be unpredictable but at least won’t accelerate dangerously.

The newer autonomous cruise control systems use cameras and may disable itself if it can’t “see”. It’s not “dangerous” but more that it doesn’t have the information it needs combined with liability issues.
