I did a quick search but didn't see anything mentioned about this topic. Do the brake lights turn on when you are slowing down via regenerative braking? If it does not, then wouldn't it be safer to have it do so, especially on the freeway? Some people really like to tailgate and if you suddenly slow down but your brake lights do not turn on, it may be inviting an accident. I do know that the little Model 3 image shows the brake lights when you actually brake or when you have hill assist engaged, but it is hard to tell if the brake lights are on during regen braking because the model is viewed from the top down and not from the back like when you are sitting at a stoplight.
