Our Silver Model S accumulates fine black soot on the rear of the car. Given the light color, it is quite noticeable. It starts to accumulate as early as a day after a hand washing. After a week it really needs washing.
Probably not from the car's exhaust. Considering I rarely use my breaks, could it be break dust? Or is the car forming such a vacuum at the rear that it pulls ICE car exhaust out of the air?
Does anyone have any idea where this is coming from?
