Wouldn't it be more reasonable to just issue the fine to the owner of the car? The owner allowed the person to use their car and accepts that responsibility. If it was stolen, then just say so. Even in the case of fleets, someone is responsible for know who is operating the vehicle and when. The gov't shouldn't care about it any further than holding the owner responsible. If the owner doesn't want to rat out the actual driver, then the owner takes the hit on points/fines/whatever
