This is only a problem in some EVs. Teslas, for example, illuminate the brake lights correctly when regenerative braking is used. The pinned comment on the video also suggests Hyundai may have fixed this on their cars by now, although I don't know whether they followed through.

IIRC the industry went from hard regen "may illuminate" -> "shall not illuminate" -> "must illuminate". Some cars designed and/or type approved when the middle one was regulatorily current follows it.

"Correctly".

Manual transmissions (and sport shifting automatics) of most cars from 1904-2024 of sports coupes to trucks don't illuminate the brake lights when engine braking. Drivers following cars should be basing most decisions based on relative speed based on these existing.

If you were to follow behind me in my 2004 manual sports car or a 2021 automatic and only applied brakes when I did, you'd be speeding in my neighborhood and rear ending me, as I keep both in second gear and it keeps me at 20mph.

lol. my definition of "correctly" differs from tesla (and probably the engineering groups that recommend this).

I think it should be a setting so that you can make it come on only when you touch the brake pedal.

on twisty roads, this is especially annoying.

You are basically crying wolf, and other drivers will be desensitized to your brake lights, possibly when you really use them.

Having no brake lights for regenerative braking sounds incredibly dangerous. Regenerative braking can slow the vehicle down quite quickly, and as the name "one-pedal driving" suggests, it's common to barely touch the brake pedal at all.

Perhaps a better version of your complaint is that Tesla has made the threshold for the brake lights too sensitive; but I would be curious how much observation went into drawing that conclusion.

I drive my manual and auto cars like this, downshifting instead of using the brakes and preventing dangerous acceleration. I often only use the brakes from 20mph and below (though may touch them during a downshift)

Thinking it's more dangerous is odd as it's a great example of fail safe.

You are basically crying wolf...

I think you misunderstand, or just don't understand at all, how regenerative braking or one-pedal driving works.

[CorrectHorseBat]

Why would it matter to other drivers whether you brake using regen or your brakes? Either way you're slowing down.

On a twisty road, having the driver behind you back off a bit more sounds like a benefit.
