Of course there's a chance of defending on an ID issue, but there is other evidence - such as statements you have made - or the case would not have been filed.. But like my colleague before me, why would you ask this question here if you have a lawyer?
You are LIABLE for all of the damages caused by your car as you are the registered owner, so you can still be sued. The exception (and it is too late for you to fabricate that now) would be if the car was stolen and that driver was involved in the collision. So you escape the Criminal and DMV APS actions but not the DMV Financial Responsibility unit or the insurance companies.
I will be happy to speak with you at no cost with a phone or office conference. Please call my office at 619-231-0401 or visit my website at www.paulneuharth.com
The bigger issue is the ID in court, not so much the fact your name was not on the police report. If you have a lawyer, ask him/her. If you don't trust the lawyer you originally hired, perhaps it's time to hire the best, locally experienced, criminal defense attorney you can afford.

Fight it. Make them show you how they expect to prove ID.
This reply should NOT be considered a legal opinion of your case / inquiry. At this time I do not have sufficient factual/legal documentation to give a complete answer to your question and there may be more to the issues you raised then I have set out in my brief reply
