That sucks

Generally speaking, it's best to always file a report. Sometimes it can take a day or 2 for injuries and damage to show up, and it's much easier to get a report up front. Given his reaction, I'd also want him to have been written up. I know you feel like it was an accident, but car drivers are responsible for looking and not hitting anyone or anything, even if it's in their blind spot. If you change lanes, and hit a car that's in your blind spot, you're still getting the ticket. I can't believe he *#$%$# yelled at you for denting his van!

That said, when you're in that kind of situation, it can be really hard to think straight and figure out what you should do. So, DO NOT beat yourself up for it. You probably still have the option to file a report, if you want. And take care of yourself!! That's a tough thing to go through.
