The radar detector = police car detector right?
Will police cars ever change their radar system to put this dectector out of date?
Thanksss.
Can't answer specific questions about Canadian legality, all I know is that they're illegal in most provinces but I have no idea which specifically.
A radar detector is not a "police car detector." What they will detect is radio waves of specific frequencies if and only if the cop is actually gunning traffic.
There are a hell of a lot of ways for cops to defeat detectors.
One is if they have a detector-detector (I think it is/was called "Spectre." Radar dectectors 'leak' specific frequencies of radio waves themselves). Some detectors offer some sort of 'stealth' protection of these but the newest detector-detectors can pick up all but one of these stealth detectors. Cop can pull you over if his sniffer picks up one of these and he probably has probable cause to search your vehicle if so. Again, not sure about this.
Two, 'instant on.' Meaning, they selectively use their guns on individual cars. Very hard to pick up when a cop is doing that but possible, there obviously has to be traffic in front of you for him to gun.
Three, microburst guns. They emit small pulses of radar that most older detectors can't pick up since they are pulsed faster than the detectors reaction times. There is a mild legal loophole about these regarding cop having to switch over to conventional radar in order to write ticket at least in the States. But guess who's home turf is being played on?
Four, as already mentioned, laser (aka lidar). There are detectors that can pick it up. But, essentially when they go off it's too late unless you have some passive or active lidar defenses (active are already illegal in at least 9 states).
Five, VASCAR (Vehicle Average Speed Computer and Recorder). A completely non-radio-wave method of calculating speed. Cop measures distance between two set points along road, which can be anything. He sees your car pass one, flips switch, sees it pass second, flips switch. That records time, the distance is known, speed is calculated and Cop can determine time or speed first, meaning, if he sees you coming he can flip the switches whenever he sees you passing things, then measure the distance afterward. It's dastardly, the only defense is to know he's there.
Basically, if you observe the "California Rule" you'll probably be better off. = You can drive as fast as you want as long as someone is driving in front of you faster. (But then there's the Flying Cops in planes, they will have a pack of road cops on the highway and will call cars in and they wave them ALL over).
