THis guy is noted as the contact person for questions related to MVC proposals. I'm not sure if he's the guy to talk to about compelling new proposals, but he is listed on existing proposals. The title sure sounds like he's the right guy.
Steven E. Robertson, Director, Legal, Legislative, and Regulatory Affairs, Motor Vehicle Commission, 225 East State Street, P.O. Box 162, Trenton, New Jersey 08666-0162
Also, there is a public meeting on the second Tuesday of the month in Trenton. It's probably for public comments on existing proposals, but if someone will be around and has the time, they may be able to ask around to find out how to get the MVC to consider new proposals.
