I am reliably informed that a GATSO cannot detect any speeds in excess of 157mph.
Is this definite? Not that my car can reach that speed!
Wasn't the Top Gear figure higher because if the camera flashed the vehicle was still in the second picture. Thus it could be deduced the the speed must have been at least n mph?

"Tolerances
In obtaining Home Office approval the accuracy of the Gatsometer speed camera system was demonstrated and independently evaluated as being within the required ±2 mph for speeds up to 60 mph and within 2% for speeds above 60 mph whilst operating within the temperature range -20°C to +60°C. The approval covers the measurement of vehicle speeds up to 155 mph."

So, if you drove past a camera at 180mph, would you escape a fine and ban ?
If so, then you should be glad you have cameras instead of real police enforcing the speed limits...
A camera won't use a high-performance Crown Vic to pull you over...
I think the forward facing cameras have a much lower limit. I have been riding my bike through a forward facing camera - for simple amusement - and at first the speed was up near 170 but more recently I've been through at around the 100 mark and nothing happens - or if it does I've past so I can't see it.

But, haven't people been done for 32 in a 30???

Obviously this was on a test track

Hmmm...lets see - the GATSO takes two photos. In one, there's a car. In the other, there's just this cloud of dust raised by it's passing.
That might just count as evidence of a silly speed!!!

I have never see that, I've seen 34 in a 30 to be sure.
Incidentally according to the Police Scientific Development Branch Handbook on Gatos they quote a permissible accuracy of +3/-5 mph

obviously we will never get done on fwd facing without a front number plate
