I only use the brake pedal when sitting at a red light because the Bolt doesn’t illuminate the brake lamps once you come to a complete stop with one peddle for some dumb reason
Surely if you are at a complete stop you don't need the brake lights to be illuminated as you don't have to warn anyone you are slowing down. If you applied the handbrake your brake lights wouldn't come on either.

Have been rear-ended before in your suggested scenario.

Maybe drivers are more polite/informed in the UK? In the US you're asking for someone to think the light is green and you're accelerating. It's the same reason I was taught to never hold a manual transmission with the clutch and accelerator in addition to not burning out the throw-out bearing prematurely.

If you are driving aggressively on a curvy road in Unbridled mode, with 1 pedal driving, will lifting before a corner act like a downshift to slow you before accelerating into the turn?

Yes. You will get smoother instantaneous transfer of forward acceleration to braking without the corresponding rev in RPM's. The motor and car will both actually slow down creating an immediate deceleration force that can seamlessly transition to full forward acceleration just by moving your foot in the other direction. Think of it like driving a go-kart without brakes.

It won't be limited to unbridle either. You'll get the same feeling in all modes I would expect, just to varying degrees.

Brake lights should really become "smart", and use deceleration detection. That's what their purpose is -- to warn approaching drivers that the car ahead is slowing down or stopped in a lane of traffic.

If you can't tell whether the car in front is stopped then in my opinion you shouldn't be driving

Have you ever driven a winding mountain road, where you come around a curve to find traffic stopped and you have to slam on the brakes? That's an extreme example, but it's the type of more sudden situation where seeing those bright brake lights helps someone react quickly.

Or when it's foggy, or nighttime, or any conditions with poor visibility.

Obviously just toodling around town in daylight and good visibility, brake lights while stopped is overkill. It's more for when the situation isn't as perfect.

Bad idea. If you are on the highway and you let off the accelarator i wouldnt want the brake light to come on

Obviously it would need to be set to detect the degree of deceleration and kick in when it's more than just slight coasting slowdown. The point is if regen is acting like the brake and slowing someone down more quickly than coasting would (i.e. at a pace that means braking is applied in any car not using regen), then it should mimic that. Otherwise we have a mix of cars running around that slow quickly WITH the brake lights coming on and others WITHOUT the brake lights coming on. That's gonna be dangerous.

You would have to link it to regen. Regen is useless on the highway, so if regen could be off if you are reaching speeds of 50+ then the back lights dont turn on. if regen is on ideally speeds 35 and under brake lights will come on. When i downshift i lightly tap the brake to show im braking otherwise when im on the highway and i downshift i dont touch the brake unless i really need to be braking

Really no need to do that though. The whole point of brake lights is to show the vehicles behind you that your vehicle is slowing significantly (or stopped in traffic). I think it would actually be better for the brake lights to work consistently that way, regardless of what method is used to significantly slow the vehicle. To the drivers behind you, they don't care how you're slowing the vehicle, they only care that the vehicle is slowing significantly.

Agree - the BEV regen and one pedal driving are new to me and cant comment but at the end of the day, if the car is slowing down enough automatically AND at its rate of deceleration other cars around need to slow down too, to avoid an accident or be aware, then yup brake lights should come on. Otherwise we as drivers have to manually tap the brakes to let people behind know and makes no sense. I can think of several situations where if this is not implemented correctly (safely), I might not want to use that feature.
