We talked about that too now that I think of it. All EV/hybrid vehicles will still show brake lights on regen.
Sort of. On my EV, the brake lights will only come on if it's in max regen mode. In regen modes 1-3, the brake lights will not come on. Regen mode 3 is pretty aggressive, but not as all in as the full regen mode. I'd drive around in regen mode 3 most of the time just because of the brake light thing.
