20. The radio would be computerized, but you'd need to install 
    64 Meg of RAM, a new sound card, a game card, a new video
    driver, a CD drive, and type C:\radio\talk\rush*.* to get
    it to play. 

19. The entire engine wouldn't be in the bay at once, and the 
    car would have to keep stopping and starting to load in 
    the relevant parts. 

18. The speedometer would read 70 even though you are only 
    doing 50. 

17. You would have to have a full service every 500 miles. 

16. Your car would refuse to start with a message
    "Abort, Retry, Fail?" 

15. For some reason the engine controller would need a 1G 
    hard disc and would take 5 minutes to boot up. 

14. The steering wheel would be replaced with a mouse and 
    you'd need to memorize the keyboard short-cut for "Brake". 

13. A particular model year of car wouldn't be available 
    until after that year -- instead of before it. 

12. They wouldn't build their own engines but form a cartel 
    with their engine supplier. The latest engine would have
    16 cylinders, multi-point fuel injection and 4 turbos,
    but it would be a side-valve design so you could use 
    Model-T Ford parts on it.  There would be an "Engium Pro" 
    with bigger turbos, but it would be slower on most 
    existing roads. 

11. The air bag system would say "Are you sure?" before 
    going off. 

10. New seats would require everyone to have the same butt 
    size. 

9. We would all have to switch to Microsoft Gas. 

8. The U.S. government would be forced to rebuild all of 
   the roads for Microsoft cars; they will drive on the old 
   roads, but they run very slowly. 

7. The oil, alternator, gas and engine warning lights would be 
   replaced by a single 'General Car Fault' warning light. 

6. Sun MotorSystems would make a car that was solar-powered, 
   twice as reliable and five times as fast, but would run on 
   only 5% of the roads. 

5. You would be constantly pressured to upgrade your car. 

4. You could have only one person in the car at a time, 
   unless you bought a Car95 or CarNT -- but then you would
   have to buy ten more seats and a new engine. 

3. Occasionally, your car would die for NO apparent reason 
   and you would have to restart it. Strangely, you would 
   just accept this as normal. 

3a. Occasionally, executing a maneuver would cause your car 
    to stop and fail to restart and you'd have to re-install 
    the engine. For some strange reason, you'd just accept 
    this, too. 

2. Every time the lines of the road were repainted, you would 
   have to buy a new car. 

1. People would get excited about the new features of the 
   latest Microsoft cars, forgetting that these same features
   had been available from other car makers for years.
