Ok i’ll bite. Because why? How can you decelrate quickly enough to need to notify the driver behind you without braking?
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.
Perhaps when EVs use regenerative braking, they should display their brake lights. Use brakes, show brake lights, same rule as before just enforce it.
I would like to share this with you: https://youtu.be/U0YW7x9U5TQ
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.
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.
