Software is the answer to many of the mechanical issues too though. Granted, the physical engineering is definitely over engineered, but would they really need to have 6 different taillight frames when LEDs can be multicolor and just tuned with software for each market? I also see zero reason why manufacturers can’t start from a base and tweak for different market configurations; you see car companies complain about complex regulation, but in the say and age when east Asia can make you anything, that’s not an excuse I’m willing to be fed.
