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.
I feel like if your car is doing anything to actively slow itself down (as in apart from just cruising) it should turn the brake lights on.
Yeah, just have an accelerometer that triggers them
Or just have it come on whenever you lift off the accelerator. I like how some cars flash the brake lights under hard braking as well. That should be more standard.
I think the flashing is actually when an assistive system triggers the break
