The false plate is probably indicative of why he didn't stop. He knew he was in a car with an illegal plate, probably a stolen vehicle, and so would have ended up in jail, probably, had he 'fessed up.

Your car will be well again, cars can be fixed. And that driver will have your car on his conscience to add to whatever reasons he was driving badly in a car with invalid plates.

Count yourself fortunate, cars can be fixed, people cannot! And you are safe and sound and well enough to be angry!
