Why haven't car manufacturers standardized automatic brake lights when a built in accelerometer detects deceleration? (lemmy.world)

Because deceleration is not braking and conflating the two is extremely dangerous.

Think for more than 2 seconds plz

The issue is with regenerative braking and single pedal operation of EVs. Many vehicles today will essentially brake if you aren't on the accelerator.

Personally, I think it's a gap in design/regulation. But not as simple as brake pedals.

This would basically mean that the brake light would stay on almost all the time that you weren't actively accelerating.

As I understand the idea of "single pedal operation", taking your foot off the accelerator pedal initiates regenerative braking. If your foot is not on the accelerator, you are braking, and the brake lights should be illuminated. But the brake lights are normally controlled by the brake pedal. You are braking without touching that brake pedal; the lights will not come on.

OP is trying to solve that.

I suppose the main bulk of people misinterpreting op is due to how most people don't think of EVs as the default and as someone who lives in a part of the US where EVs are pretty rare I assumed Regen braking was activated by pressing the brakes but hey I guess that goes to show my lack of ev experience and motivation to think about how driving one works due to how rarely I come across them and have the opportunity to even consider buying one
