@4f50b305 @ac377c46 @4206c9f7 modern cruise control in cars know when the tyres slip and turn off, the cruise control of the last century just kept a constant speed based on the speedometer.

I don’t know about big rigs, but I would bet the newer ones are the same, problem there is the trailer, if it “breaks loose”, you’re going for a ride.

People fail to understand that no matter what, all you have is the very bottom of your tyre touching the ground, that’s it.
