This shows one of the main issues I have with both cameras and radar guns, that they are purely for money making rather than safety.
If safety was the primary concern, then an office with a radar gun would arrange to stop the motorist, give the appropriate fine/whatever, and send them on their way hopefully with a little more caution and attentiveness to their speed.
Radar guns and cameras, with multiple ones on the same stretch of road, are happy to let the motorist continue at whatever excessive speed they are doing and collect the money.
I've wondered before what legal recourse there would be if, for example, someone was clocked for excessive speed by two cameras/radar guns along a road, then a mile further down the road they killed someone due to speed. They are already on record as breaking the road laws twice, yet due to only retrospective action they continued to cause death/injury.
Not excusing speeding, I just think that cameras/radar guns don't actually serve any purpose other than making money - unless you're going to stop drivers who are speeding, give them a stern chat and something to think about, then are you making the roads safer? Sorry, /rant
