    Ok i’ll bite. Because why? How can you decelrate quickly enough to need to notify the driver behind you without braking?

      Engine or regenerative braking can very quickly slow down a vehicle but may not activate the brake lights depending on the manufacturer.

      Or crashing, I guess.

      EVs have regenerative braking, where when you let off the accelerator, it immediately starts slowing down, quickly. But the brake lights don’t come on. This would make driving behind EVs safer.

      Other than regen braking like everyone said (which really slows down a car almost effectively as brakes when set to the highest regen setting; look up “one pedal driving”), you can also slow down a car quite rapidly in a manual transmission if you skip a gear or two when downshifting. No brake lights come on when you do this, and honestly I think that they should.

      Jake brakes in big trucks, but most of them do show brake lights now even though you just coast to activate them. Some drivers like to turn them off because it makes you look like a dangerous rookie in the mountains if your brake lights are on consistently while going downhill.
