The thread on noise for electric cars reminded me of one other thing they need. A yellow warning light in the CHMSL (Center High Mounted Stop Light), to warn drivers behind that they are using regeneration mode to slow down, and not the brakes.

My plug in hybrid, like most, has almost one pedal driving, with the regeneration mode working. It slows down about like normal braking speed until I hit the brake for the last 10 feet or so, finally energizing the brake lights. I keep a pretty close eye on drivers behind me to be sure they know I am stopping.

Hard to believe no one has addressed this yet. Most BEV drivers seem to do the same thing around here, where Tesla's are pretty common.
