Just wondering how the brakeklights are connected. Doesn’t matter if it’s physical or recuperating braking in this regard.
in an classic ICE car enginebraking will never turn on brake lights, footbraking no matter how little always will.

So in an EV: if recuperating is ON, it behaves like enginebraking, therefore no brake lights I assume. When foot braking they are on, again I assume.

But: If the car by itself slows down for upcoming traffic it can be braking quite fierce. More than we might brake by foot to slow down a little in other situations.
in fact, the amount of deceleration could in certain situations be exactly the same but either triggered by either sensors or by foot.

Do the brake lights behave the same then? are they triggerd by the amount of deceleration? And/or by foot-braking?

On, always on.
So, if you have recuperation ON. Say you drive on the highway and release the throttle, th brake lights are turning on? Sounds dangerous actually cause it can trigger a chain reaction behind you

It’s better than no brake lights if you’re slowing down. Best to have people slow down behind you.

True but excessive. Enginebraking and even truck-retarders do not make brake lights. This is what the world is used to.
I’ve seen accidents happen because people panic at brake lights and overreact causing a chain reaction! But you’re right they at least don’t run into our beautiful Taycans ;D
o well. It’s the new standards to be, probably even regulated in some car production laws

They don’t. There’s a threshold of when they do. Basic recuperation off throttle doesn’t trigger it.

That sounds way more logical!! Just like enginebraking your ICE car
