Hit and Run!

Yeah seriously, if he almost got ran over ? But I agree with the others, it's not worth getting your self injured or possibly killed just to get revenge. And as you said, there wasn't any damage so it really isn't as big a deal as say he had a big truck and totalled your car then took off. You did the right thing to get his license but that's all you need. When you give it to the police tell them the story (add in that he almost killed a cop) and they will handle the rest. Tell them you'd be glad to testify and you'll get your revenge in time.
