This happened to my daughter over a year ago, exactly the same. She tapped the back of the other car with absolutely NO damage to either car and before she knew it she had a claim for all sorts of damage to the other car and whiplash to both the driver and her baby daughter!!!!
this has been dragging on now ever since. The other driver got their own inspection of the car done LOL!!!!
I remember a post quite some time ago with peeps of this board condoning this sort of behaviour well chaps this is the down side
