The two best things you have going for you.
1. Cop watched an uninsured motorist drive off.
2. As was mentioned, Jury Trial.
Now if your lawyer could drop a bug in the Cops ear that watching an uninsured motorist drive off will be an issue in court, then the Cop would be a fool to show up. In other words he will beg the DA to dismiss the case before the first day in court. But if that happens you lose leverage in a civil trial which would be the only way to get a judgment against the other driver.
If it were me I'd take the dismissal, a judgment doesn't mean **** really.
