An idea that I think would revolutionize the safety of motor vehicles is to install radio frequency emitting antennas within cities so that cars are speed limited to the pre-programmed speeds.
For instance, the downtown miami area would be blanketed at 25 mph . All cars entering the downtown area would automatically max out at 25 mph. (except for police and rescue vehicles) .. =)
Mall parking lots can be set to 5 mph. AWESOME !
Think of the savings in fuel economy alone !
Highways can be set to the maximum safe speeds, the reduction in fatalities would be enormous.
All new cars would be fitted with the receiver unit from the manufacturer, therefore guaranteeing that they will operate within the guidelines of the speed control system.
