Several years ago - I was stopped at a red light in our 2012 S P85, in the left turn lane, along with a lot of other traffic also stopped waiting for the light to turn green. While I was stopped, I was rear-ended by someone cutting across lanes, trying to get into the left turn lane - damaging the passenger rear portion of the bumper.
A week later, I was stopped at a different light - in the middle of a long line of 3 lanes of traffic also waiting for the light to turn green. As I was inching forward (along with the other traffic), the car behind me accelerated and hit me full-on the rear bumper.
It took months for the body shop to get a replacement bumper from Tesla - and since then, haven't had another accident.
