Yes, in all EVs now they must activate the brake lights if they are decelerating at a certain level of G-force. I can't remember the exact level, but it's mandatory that they do this, because, just like with a manual transmission, you can decelerate with the engine alone, and it's not fair to the drivers behind you to surprise "brake" with no indicator or brake lights.
