I know the gen 1 Leaf does not illuminate the brake light when doing
regen, but then again it's regen is at most like engine braking in an ICE.
I think the main take-away is that you can't count on everybody to have
working brake or tail lights, and need to maintain proper following
distance.

I don't use 1 pedal mode in my Ford Lightning, but from comments on that
forum, the brake lights come on in moderate regen (either from 1 pedal or 2
pedal mode).

My 2017 Bolt does not operate the way you describe. Whenever deceleration
is greater than normal engine braking in an older ICE vehicle the brake
lights come on.

when drivers use strong 1 pedal regen driving in traffic the brakes
lights do not come utill the last 5-10 miles per hour to total stop.
this can cause possible rear ending. I'm used to following gasers that
there brake light show much more. my older leaf has weaker regen so I
must use brakes , which shows drivers behind me, i'm stopping or slowing.
i also flash my brake lights when slowing in heavy traffic.
someone needs to work on a fix for brake lights to come on under heavy
regen.
