Someone living the opposite side of the road backed a car out of his front garden driveway, across the opposite curb/pavement and into my 4' length of brick wall and my neighbour's 6' high brick gatepost and demolished both. There was surprisingly little damage to the cars bodywork - a minor dent in the metal bit of the tailgate and multiple scratches on the plastic bumper. A couple of bricks had gone through the back window and ended up in the rear seats.
Most of the debris remained where it toppled but bricks from the top of the wall and the top pillar did travel 10' or more.
Luckily my car and my neighbour's car were not parked in our front gardens at the time.
