Back in the day, a bit of tape was needed on each headlight to prevent blinding oncoming traffic when driving a LH drive car in a RH drive country and vice versa. Do our supercomputers on wheels need such a bodge job or can the angle of the beams be adjusted via the User Interface?
Noone cares in the UK - probably because everyone there drives with crappily adjusted headlights anyway. I drove for 5 years in the UK with my LHD and did not get once asked about this by police ( and ive been stopped a couple of times for various reasons). AFAIK Teslas actually adjust their headlights automatically going from LHD -> RHD and vice versa. If not you can just drive to a wall. Tape the wall where both headlights are and then adjust them to each others opposite.
