Use case "Access to data stored within a vehicles computer system"

Proposed Use Case #2  draft by Jeff Stollman

Sticking with the automobile theme, I am concerned about authorization to access data stored within a vehicles computer systems.

As autos become smarter and more of them have built-in navigation and emergency communications systems, the data accumulating in these systems becomes increasingly personal.  The data is of value to many parties.  At a minimum these include the following:

1. the vehicle "owner" 
1. who may need emergency assistance
2. who may want to look up some historical facts of his travel (distance traveled to a client site that may be reimbursable)
3. who may want to update the information when he replaces parts or performs maintenance
4. who may need to prove that he wasn't the driver when the car caused an accident or was used for criminal purposes
5. erase his personal driving data when the car is sold or junked
2. the mechanic 
1. who may use the information for diagnostic purposes
2. who may update the information with parts replaced, maintenance performed, or accident information
3. the vehicle lessor (in case the vehicle is leased and not purchased)
1. who may bill by mileage
2. who may charge a premium for driving in certain areas (e.g., foreign countries)
4. the insurance company who may charge lower rates for safe driving behavior
5. a prospective second-hand buyer 
1. who want to know both the driving history 
2. the maintenance/repair history
3. the accident history
6. law enforcement
1. who may use the information to investigate an accident
2. who may use the information as evidence of negligent driving
3. who may use the information to track a vehicle
7. the auto manufacturer 
1. who may use it to detect flaws
2. who may use it to improve future models 
8. wrongdoers 
1. who may use it to track down their victims.
2. may attempt to falsify the history to avoid insurance liability (e.g., in an accident)
3. may attempt to falsify the history to improve resale value
4. may attempt to falsify various information to disguise auto theft.
9. other vehicles
   1. as they transmit basic safety information between vehicles to facilitate warnings to drivers concerning impending crashes
10. infrastructure
    1. vehicles may transmit safety information to infrastructure (signals, road-side signs, alerts signs) indicating some information that they may want/need to know

Unlike Ingo's use case which appears only to require uniquely identifying a vehicle, this scenario requires selectively authorizing read and write access to a large amount of personal data by a variety of parties.
