This may seem petty, but by simply making the turn signal amber, it could improve visibility a lot more. Also making the turn signal on the same circuit as the taillight is what I call "Bad Over-Engineering". "Bad Over-Engineering" is when someone over-engineers something but end up not making it any better than it would if they did it simple. Besides, every other Model S not sold in North America has ambers. Go figure. Furthermore, in a survey, most people prefer to have amber indicators in the rear according to a TMC post: Amber rear turn signals? So did Tesla put amber rear turn signals on the Model X? It would make sense because of how much they advertise safety on the X. I already confirmed where the brakelight, taillight, and reverse light is, but amber turn signals can be possible.
