Reminded me of this Technology Connections video, in which the dude explained (among other brake-light related things) how some law allows electric vehicles to get away with not using their brake lights: https://www.youtube.com/watch?v=U0YW7x9U5TQ

I’m kind of surprised he made absolutely no mention of manual gearbox vehicles. Some of the problems he’s describing predate EVs and adaptive cruise. I have a manual car and motorcycle. I pretty regularly apply just enough to the brakes to turn the light on without engaging them during engine braking. Engine braking depending on gear choice can be pretty strong. Likely not as aggressive as a regenerative braking system but more than enough to cause issues. I’m certain I’d have been rear ended if I didn’t make the lights turn on while just slowing down, not coming to a full stop.

Yeah my electric 208 is kinda like that (if I remember the video well, watched it a while ago) but since it's Europe there actually is a regulation about how much a car can decelerate before break lights come on, so instead of making the system turn the lights on they throttle how much it can decelerate for recharge and still makes you use the break to use full regen (and eventually the actual brakes, of course). So it's not a real "one pedal driving".

First of all, this would be illegal in many countries.
Second of all: we can differentiate cars by: has red lights, back.
If we lose this option we can no longer differentiate easily if there is a car coming towards us or driving away from us.
They tested using a green light for the front brake light, not a red one

I don't understand this at all. Why do I, as a person in front of a vehicle, care whether or not it's braking?
