For years it has been possible to set up cameras to take pictures of cars as they speed along highways, jump lights or drive too fast down the street.
    However, even if the pictures are taken automatically, someone still has to do all the paperwork of issuing fines. But now a British company called EEV has come up with a computerized video system that can do it all automatically.
    They suggest that all number plates have a bar code as well as the usual number. The bar codes are just stripes of lines like those you see on food packets but bigger. EEV’s high speed video camera system can read a bar-coded number plate even if the car is doing over 100 miles per hour. The computer controlling the system could then use the information from the bar code to find out the name and address of the driver from the car records, print out the fine and send it off automatically. The inventors also suggest that the system could watch traffic to help catch stolen cars.
    The new electronic system could be watching everyone that passes the cameras! Many people find the idea that "big brother is watching you" is more of a worry than a few motorists getting away with driving too fast. Besides, some people will be very unhappy to realize that with the new system, the police could find out where a particular car has been.
