Well I went past one the other day, was on the opposite side of the carrigeway but pointing towards on comign traffice, parked right up the curb on the verge! Bastids! So i assume they can get u on either side of it and from where the one I saw was parked you dont see it till you come round the bend on the carrageway I reckon they have a fairly big range, shame was not in my turbo so couldn't tell if the road angel could pick it up or not. Still, I think I was doing 65 odd in 60, heard nothing, plus, how do they flash you? I assumed it would be like a police with there gun and just clock you etc
