What we need is a "Little Bobby Tables" vanity plate that exploits a buffer overflow in speed cams.
Isn’t there an xkcd abut a license plate of zeros an Os and ones and LS and the cops just say “it’s the guy with the plate again”.
Unfortunately they seem to filter special characters on input, that is, when you apply for your plate.
But don't despair! Depending on how crappy the cam's firmware is, NULL might just do the trick.
