The police car detectors only work in cases like the California Highway Patrol, where the car <> base signals use Low Band VHF, and in each car the signals are repeated on a higher frequency, one that works better for handheld radios. There is still a lot of empty space in California, so it's easier to carry your repeater along with you than build a system that can pick up watt level signals on every lonely highway.
