I envision a concierge service, with a low monthly fee or high one-time usage fee, for road side legal and technical counsel. If the car is already driving, why should a a passenger know which rule the car was following at the time an officer said a moving violation occurred. The concierge could access the car's driving records on the fly and provide specific reference to traffic laws at that specific jurisdiction. The officer and the concierge could hash out the entire interaction roadside and it could recorded. Meanwhile, the passenger/"driver" would be sitting there mouth shut, hands on wheel, and hopefully not attracting any attention beyond the moving violation.
