It’s not a perfect solution for EVs and Hybrids that can slow down quickly without pressing the brake. Technology connections has a full video on the matter, but basically things need to be updated for current tech if we want to avoid accidents due to information not being relayed to other drivers.

There are EVs that handle this by using a deceleration threshold, but that is not the same as just strapping an accelerometer to a car.

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

I’ve driven rentals that put the brake lights on if you did not have a foot on the gas, and only lit a 3rd brake light when actually pressing the brake. Dunno why it isn’t more common tho.

Because a think called a “brake light” should light go only to indicate braking?

To be fair, that’s what the 3rd light that only lights up when the brake is applied is. 😌

Reminds me of the cars that now have the reverse lights on when they’re just in park making me think they’re going to back up but never do.

Yeah I’ve had so many Chevy’s spoof me into thinking they were backing out of a parking spot only to realize they weren’t, infuriating

That’s stupid feature on American cars only and they’ve been doing it forever.

Standardised is a funny word, a car manufacturer doesn’t standardise. Laws and 3rd parties like ANCAP do.

When they need to do it to sell it with certain safety requirements, they will.

However, even if those happen, and car makers today start building them with that, it’ll take a decade or longer before you’ll start seeing them in majority on the road. So even if you lobby for it, expect time since I’d say less than half of all people buy new cars, so it’s not until the second hand market sees it will it be commonplace.

Right now the second hand market is starting to see things like collision avoidance systems and they will often flash brake lights when emergency braking on behalf of the driver.
