I stopped once when I saw a girl in a Honda Accord trying to change a tyre and asked her if she needed help and then her BF popped up from behind the car and abused the HELL out of me, threatening to kick the panels in on my car etc, from that day on I will never stop for someone unless they actually flag me down for help or I can see they are injured, unforutnately theirs too many tools out their.
Anyway hope you get the car all fixed up with no hassles dude, lucky it wasnt a worse crash.
