the problem is that the camera did not see it and also not the reverse sensors.
I never rely on just the tech in my car, every single time I take notice (visually notice) what is is surrounding the space that I'm reversing into. But saying that, that tree branch should never be anywhere near where vehicles are parking
The main thing is that are okay (yes it's only a little ding). Dam it, you've not had that car long as you were involved in another accident a year or two ago.
Luckily for me, I've never ever been involved in an accident and no I'm not 'Driving Miss Daisy' lol
