I received an email from the California Bicycle Coalition that might be interesting:
EVERYONE is invited to Complete a Survey to express your opinion about this proposal.The California Bicycle Coalition is pursuing a bicycle-oriented special interest license plate program for motor vehicles in California. License plate programs can make millions of dollars for programs that can help get thousands more people to ride bikes
Here's some more information:
The DMV Website has examples of current California specialty license plates.To implement the program, 7,500 plates must be pre-ordered within 12 months. If the pre-order quota is not fulfilled, all dollars will be returned.
