Mobile speed camera yesterday, but i was ok. They were cleverly after some folks doing 34. Very clever placements. Anyway, it got me thinking: what are the ways of being caught? I mean, there is the mobile camera out the back of a chevron dazzle camourflaged van. That is one type of camera which can catch you. Then there are the usual fixed cameras, the yellow boxes on posts. But then is that it? Or what about those other things on posts that look like loudspeakers? What about the speed sign with the happy or unhappy face? I mean, could i never pass a mobile camera or fixed camera, or average speed camera set up, and still get a ticket, and if so then what could be the source of that? In short, what else should i watch out for which could nab me if i was going a momentary touch over, which is all i ever do if i speed. Maybe an unmarked car behind me or towards me?
