My husband had a similiar incident ,he was waiting to exit a road,when a Silver Astra van overtook him on the LEFT,,broke left side of back bumper and scraped off paint.it was going at a speed,,fortunately,the car behind us got the number plate,
We reported it to the police and as the guy was speeding,should not have overtook on the left,going up the pavement to do so and failed to stop...the police are interested in getting him.
Oh they have,and we now have his insurance details...just waiting now.
Although no-one was hurt ,the police were very helpful ,
