Here is my fear. I see all these news stories about cars with sensors and computers in them; they can see in the dark and apply the brakes before a driver can and they can keep us from bumping into the cars around us on the road. Heck, they can even parallel park for us. This, my friends does not pose a threat to our safety on the road. It does, however, pose a real threat to a major part of our way of life - the motion picture industry.
Imagine watching a film in which the teenagers accidentally hit the stranger on the highway and then horror ensues. That cannot happen anymore. Movie done in the first 10 minutes. Chase scenes where one car bumps the other off the road? Sorry Mr. Bond but your car won't let you do that. Comedies which have the inept driver bang up the other cars when trying to fit into the tight spot? Gone once a computer takes over. This spells doom for many major genres! How many cop chase scenes would be interrupted by audible alarms from proximity sensors? How would we hear the witty banter?
Computers have their place, no doubt: spaceships to Jupiter, chess matches and the Jetsons' apartment. I just don't want them stealing from me my freedom to run over Cujo if the need arises.
