The court date is for criminal purposes, I'm guessing this is not his first ticket. The only thing I could try to do is leverage my appearance in court against the $2250 he owes to me and my insurance.
Your insurance company should subrogate against the guy and try to collect your deductible back for you. Hopefully things will work out. When people complain about how much their insurance is....this is a big part of the reason why.
