"In states like Indiana, they're already using the electronic tollway passes to give people speeding tickets. How? Of course they can "clock" how long it takes you to get from one toll booth to the other to figure out your avg. rate of speed!
Not to mention the FACT that similar information is being used in courtrooms as evidence for people's whereabouts. "
Actually I think systems like this are going to go away. Speeding tickets are big revenue, but one of the reasons they can give them out is the gamble, people speed because they can get away with it most of the time. When people stop being able to get away with it they'll stop speeding, and no law enforcement agency in the country wants to lose that cash flow.
