File a report. Make sure to provide a description of the driver.

Plates can be useful but I'll be honest with you: people who are willing to behave like that aren't likely to actually register their vehicles. Still, it's worth a try! At the very least you'll have a report for your insurance, even if the offense goes nowhere.

It's not uncommon for people to shrug off the offense but simply request a report for their insurance.

I'm sorry someone was a dickhead to you.
