One of the best things about the range test on Sunday, was being in a convoy with 4 other Lucids.
it meant I got to see the regen based brake lights coming on (very occasionally) as we drove Ms Daisy to the beach and back (sorry
@SaratogaLefty couldn’t resist)
what I saw was mostly logical use of brake lights… eg they would come on for slowing down for corners or sudden appearance of cyclists.
What I did not see was a LOT of brake light, even whenever the person in front lifted.
the light is definitely tempered by the amount of deceleration … and in my opinion as the person following, in a healthy safe way.
I believe
@DreamPaloAlto had his GoPro mounted and running for some of it, and that should show the brake lights very effectively
