Make this correction before he stops you again and writes you a ticket that you will either have to pay or fight.
Or, if you can't go, send a registered letter, with cc to your state's bicycle advocacy group and the local paper. Cite the appropriate laws.
If you have a friendly lawyer who'd be willing to put the letter on his letterhead, it would be even better. (If you do the bulk of the research and drafting yourself, he might not charge you all that much.)
