I suspect because there’s no consistency in the brightness of vehicle lights. But that’s one of the reasons why I think an incremental light bar would be better, there’s no variation between vehicles. You could even make it more informative by flashing the whole bar when you first brake, so someone behind you can more easily see how much of the bar is being lit up.
Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates
turtlesareneat@discuss.online 2 weeks agoJapan introduced brake lights that increase intensity based on how hard the driver was braking. 20+ years ago. They tested it in the US and drivers found it to be “confusing.”

If you want that, just light up the first and last LED always.

That’s a good point, although flashing does help to grab attention, but it can also be annoying when the person is driving with their foot on the brake pedal.

If Japan introduced that they never caught on, unless it’s specific to an area or model of car.

90% of the things that Japan introduced according to comment sections on the internet never happened (or never made it past the prototype stage) and the rest was actually introduced in Korea, not in Japan.
The Japanophilia is strong with a lot of people on the internet.

Yeah I mean I’ve been commuting 2 hrs a day in Japan for almost 10 years now-- you’d think I would’ve seen these brake lights by now

probably because thats a terrible way to do it. It would be noticeable if a car started braking and then started braking much harder, but if they slam on the breaks you don’t see anything change, just a normal brake light.

Plenty of cars flash their brake lights when ABS(/ESP?) engages, which is reasonable and should be a legal requirement IMO.
There’s lots of room to give additional info in between that and “brake light is on because the driver doesn’t understand that they can do mild adjustments by letting off the gas / stupid bitch-ass VW PHEV computer thinks using cruise control downhill with electric regen requires the motherfucking brake lights”. It’s like no-one realizes or cares that brake lights lose all purpose if they’re on when the car isn’t meaningfully decelerating. ARGH.

BMW should work on making the turn signals work first.

BMWs need a speeding indication more than a braking one /s
