Two of the many things that really piss me off about speed cameras are that 1) you can be pissed out of your head but if you're doing less that 30 the camera will not get you but on an open, clear road you'll get busted for doing 34 perfectly sober and safely and 2) vehicles pulling trailers that are limited by law to 60 can break their speed limit by 10 with impunity and be a damned sight more dangerous than a car doing 80

(based on UK speed limits of 30mph and 70mph)

ps touch wood I've not yet been busted for speeding.
