You can file a trespassing report and the officer will have to follow up with the vehicle owner. If they can't provide info as to who was in the vehicle then they get the charge. The problem is to the law its a petty offense, nothing was stolen or vandalized so just a trespassing charge. They'll just say they took a wrong turn and plea it down to a small fine if they don't have a previous record. To them its not really worth the officer or courts time. But you can file a report to get it on record and it kets them know you don't play around. And word travels.
