Speed cameras trap motorists from space

How do you feel about a satellite system that uses (ground based) cameras to read your car's license plate and detect how fast you are driving? Law enforcement in the UK likes the idea very much, as does PIPS Technology, who says its system provides "number plate capture in all weather conditions, 24 hours a day." UPDATE: I incorrectly wrote that the cameras were satellite based, but the cameras are on the ground.
