That's a shame, luckily you were not hurt.
My sister was sideswiped by an elderly driver a few years ago who also hit two other cars in the process.
Everyone pulled over and while the cop was filling out the paperwork the person who caused the wreck gets back into his car and drives off never to be seen again.
Nobody took down his plate number or license and my sister tried to pursue but the front wheel was no longer attached to the axle
