I'll cut to the chase, my car was bumped hard from behind while it was parked with Sentry mode turned on. The damage isn't great, but I have really deep scratches all over the rear bumper, and it is a total bummer after just getting the entire car opticoated. Sounds like I should just be able to check the side cameras, get the plate of the car that parked behind me and contact the police or my insurance. Well not so easy, after checking the side cameras during the span that I was parked in that spot there were 3 cars that had parked behind me, it is completely impossible to tell which of these cars actually made contact while they were parking or leaving. Not having the rear camera recording make the Sentry mode useless in a situation such as this one, I can't show any prove that any of these cars actually made contact. Tesla if you're checking these forums please enable the rear camera recording available in Sentry mode in the future updates.
