re: Why don’t they make brake lights get brighter the harder you press?

Maybe with self driving vehicles it’s moot but it seems like we could have done this years ago. It would be nice to know if the guy in front of me is tapping his brakes or slamming them down.

Maybe it could go from an orange to a dark red. How has nobody gotten on this?

BMW has had multi-stage brake lights on some of their cars for ~20 years. I think the US only got 2 stage at most, the rest of the world got 3 stage brake lights that worked like this:

1. normal braking had brake lights and CHMSL

2. hard braking had brake lights, CHMSL and rear fogs (flashing CHMSL in regions with no rear fogs)

3. ABS triggered braking had brake lights, flashing CHMSL and flashing rear fogs (fast flashing CHMSL in regions with no rear fogs).

This was part of the basic dealer programming when you picked up the car and many dealers didn't even discuss it and left it deactivated.
