I can't wrap my head around why a second lessee should get something special, such as pro-rated AP. However, I've wondered if this will come up in a different way, such as if FSD actually happens, will lessees have to pay the entire price for their lease in progress.
As for "friends in Tesla" hooking up their buddies with free AP, I guess that's lucky for the buddy, but I can't help feel it's disingenuous.
