Cruise control (1 Viewer)

[Nick Vermeil]

Since I’ve been commuting by car 122 miles round trip during the pandemic, my mind wanders. 

If you’re on cruise control and you’re descending a hill, the control slows your car. Do your brake lights come on??  

 

[Joe Summer]

Many newer cars are equipped with Adaptive Cruise Control, where the brakes are used to slow down the car. In that case, your brake lights would come on.

If you don't have ACC, then the brakes won't be used and the brake lights won't come on.

The adaptive cruise will only slow you down if there is an object in front of you.  Your brake lights will not come on in either case.  The slow down is done by the computer with the throttle to keep the cruise at set speed or to keep the object in front of you at a predetermined distance.

No

If no one is behind you to see them they never come on.

Yes, it is the visual version of a tree falling in the woods.

No because it’s not using the brakes to slow, it’s adjusting the accelerator.
