well, technically right, but unfortunately, due to lying b@stards, only half true... you have to be able to 'prove' it was their fault. So grab an independant witness if you can, or don't move until the Police have arrived. If the Police don't want to come, tell them the damage is pretty bad and that you think you're hurt. Try to get a written statement from the guilty party at the scene and full details of witnesses nearby. Your own passengers are not witness enough apparently. Its bullsh!t really, but its what the world is coming to.
