LCD License Plate
Speed traps begone!

Obvious bit: use an LCD screen for your licence plate.

Sneaky bit: the screen can refresh faster than the human eye can see, so each picture frame contains only a part of each character on your licence plate (say 1/3 of it).

The next picture frame displays another part of each character, and so on, in a cycle.

With a sufficiently high refresh rate a human observer will just see the whole of each character - a 'normal' licence plate.

But a speed camera, operating as it must with a high speed shutter, will only see (at best) a picture of a partial plate when it takes its photographs.

Of course, get snapped enough times and they might have enough jigsaw pieces to complete the puzzle...

       I'm bunning this, even though there are already anti-camera license plate covers. There one that you apply like wax that makes it super-shiny so a camera will only yield a bright spot of glare from the flash in the picture.

       ...and it could be turned off when parking? If your car is then towed away, you might never get it back.
However, very sneaky, and as such, deserves +

       Well for parking, simply have a regular plate that flips down to cover the LCD plate.

       This is classic! I love it. If this could become an accepted standard for license plates across the US and Canada, you could create some really cool designs and effects with your license plate such as animating the numbers or have some sort of light chasing sequence. There would probably have to be some sort of RFID tag on the car so that the real tag number could be verified and it could reduce the obvious issues of fraud.

       What is this a solution for? The "problem" of being caught illegally breaking the speed limit? Another much simpler solution is to obey the speed limit. Maybe that's just too difficult?

       I've thought before of using an LCD display as a licence plate, but it wasn't for that reason...

       //Maybe that's just too difficult?//   

       ooooooooo I always obey the speed limit too and wouldn't condone breaking it, but what's a guy to do when he gets an idea about how to trick a speed camera?   

       If the hb was limited to only posting the best, simplest, safest or most law abiding solutions to problems it would become boring as hell.   

       On the other hand I've probably criticised others' ideas before on at least one of those grounds so you have a fair point and at least one anti-speeding anno was inevitable.

       They'll start taking three or four pictures for each time the camera is set off.

       Of course, no one will hack it so it plays a string of different numbers.
