I have been looking at many of the RC photos lately and noticed that if I were in a vehicle next to the M3 and the M3 signaled to come over would I notice? You, know haven't you been on the road next to a car and you both signal and move towards the same lane at the same time? I have a lengthy and trafficy commute every day and that happens too often and freaks me out. Anyway, especially with the wrap around reflectors being passive due to one being the charging port cover, the M3 does not look to communicate Lane change intent to immediately sideways vehicles...
