I was talking to a neighbour on my doorstep this morning when I witnessed a minor bump. Car 1 had pulled up towards the side of the road (I wasn't paying enough attention to the exact position as I knew what she was going to do). The car then started to reverse back onto the driveway. As the car reversed and turned, a car who had been behind it (car 2) kept driving up the road and hit the front end of car 1.
Car 2 said it's car 1 at fault as driver assumed car 1 was stopping behind my car to park up and didn't know they were going to start reversing.
I will post a diagram but not sure how helpful it will be!
