I followed a (what appeared to be very intoxicated) driver up through Chislehurst from mottingham and just after the flashing 20mph sign, he/she hit a dark coloured car parked opposite the school and drove off. If it was your car, or you know whose it was, let me know as I have the reg and saw what happened. Sorry, I would have stopped right then but I was trying to take down the reg whilst in school run traffic and was en route to pick up my own but I did call the police to report it and by the time I'd doubled back about 15 minutes later, the damaged car wasn't there any more!
