I've done this. Cop was happy to go to the driver's house and have a chat with him.

I also recently called the local school district after one of their bus drivers right hooked me. They promised to have a little chat with her.

Once, after a careless driver endangered my wife while we were riding, I chased down the motorist -- who could see me following her and clearly tried to ditch me. I stayed on her, then rolled up to her house, rang the bell until she came out. When I pointed out what she'd done wrong, she replied "Well, I thought you have to yield to me, since you're on bicycles." I told her she's wrong. Then I explained the economics of it: my wife's age and years to retirement, annual salary and expected salary growth, figured the sum and discounted it to the present value, then told her how much she'd owe me (judgment or settlement) if she killed my wife and I sued her. That shut her up.
