And as mentioned before, the same is true of stick shift cars that the driver has the habit of engine braking. Engine braking can also considerably slow down an ICE car and it does not turn on the brake lights in any way.
Touch the brake pedal.
But if you do come up with an electronic approach I think it would be a good idea as I have the same concern when in traffic.

I agree. We all have brake pedals. If you "touch" it the brake lights come on. You can tap it and literally flash your brake lights on and off. We also have flashers.
An electronic device would be nice too. Not necessary, but nice, as long as it were well designed.
To me, I think if someone made an automatic brake light device the brake lights should turn on dependent on speed change, not level of regen. If I'm going down a hill with the car in B mode I don't need the brake lights on down the whole hill. No other car turns on its brake lights just because the person has downshifted and is engine braking.
Either that or braking force, or both. Maybe regen can turn on only certain brake lights, or on for 3 seconds, off for 3 seconds. Then the brake pedal can turn on more brake lights, or keep them on or make some flash quickly. But again, there are times that brake lights left on, like going down a hill, aren't necessary.
This kind of reminds me of driving comercial vehicles. Big comercial vehicles many times have a braking device called a retarder. There are several kinds of retarders, and some turn on the brake lights when activated, and others do not. With some retarders it is possible to just leave the retarder set as you come down a long mountain pass, as long as it doesn't turn on your brake lights. That way, when I hit my brakes because I really need to slow down the cars behind me see my brake lights come on and realize that I'm slowing down now. But with the kind of retarder that turns on the brake lights we generally use those intermittently. Basically I speed up about 5mph, put the retarder on and slow down 5mph, speed up 5mph and then retard back 5mph. That way if I suddenly need to slow down the brake lights stay on, signaling that I'm now actually slowing down considerably.
