    Not sure if this was covered elsewhere, my apologies if it was.
    I have been wondering if the brake lights come on when using regenerative braking and your foot is not on the brake pedal.
    The reason is that the regen braking is awesome and slows the car down a lot, which is great for one pedal driving but what about the un-attentive driver behind you who doesnt have situational awareness of the traffic ahead and merely reacts to your brake lights?
    So I decided to do a test tonight and am happy to say the Tesla Engineers have you covered. The Brake lights will come on when the regen is applied and the car slows down. Once the car is coasting at a constant speed the lights will turn off.
    If you are using the low Regen setting, the brake lights do not come on immediately but only when the car starts to slow significantly. If you are going down a hill and the car is coasting at a constant speed, again the lights will go out.
    I continue to love driving this car.

    You can see the little brake lights and turn signals light up on the on-screen car too. I don't know how much if any lag there is between the real brake lights and the on-screen representation.

    Unless your car is MCR, in which case the onscreen brake lights are very hard to tell when they come on. Need to get Tesla to fix that!

    I used the rear camera to check - there is no lag between the real brake lights and on-screen. Same with the blinkers. Perfectly synchronized.

    I do have one other little pet peeve on this: you know how you use regen braking to slow down to a crawl, then finally transfer your foot to the brake pedal to halt? The brake lights don't stay on the whole time -- they turn off after the regen has tapered off and then they come back on when you hit the brake pedal. Car motion is smooth, but it must look weird to the person following - why do the brakes go on, off and on again? It nags me ... but maybe I'm just a little OCD about stuff like that.
