speeding ticket (NIP)

[nick crisp]

But I have seen some who zoom past with no fear because they DO now something I don't - which is that the next set to calculate your speed will be after they have left the M way

Except haven't I often seen them positioned at or even beyond the exit to prevent this?
If they're front facing, I don't pay them as much heed, except I'm always wary in case they've thrown another type of camera in somewhere as well. But I think they're switching more and more to rear facing cameras now. Although I'm apt to just settle in anyway if the traffic is heavy.
