Kaaaaaaaaaa..... so the jury's out, but erring on the side of "don't worry"??
It was definately a normal GATSO, or at least something in the same style body, and it gave me a nice double flash about a half to full second apart as i went towards it. Dunno what the angle of view is like on them. I'll be going back the same way for a fireworks show tomorrow eve so I'll have to examine the spot (it's quite a distinctive place) and see if the white calibration lines are on both sides of the road. If it's just on the one side i'll breathe easier.
If on both sides... well... is there a solvent that can be used to remove old road paint?

(often thought about doctoring the calibration lines in front of gatsos anyway)
Normally quite wise to both truvelos (almost always in the most completely inappropriate places, but visible from far enough away to slow down for) and regular GATSOs (never had one go off as i've driven towards it before, at any speed..), but who knows if they're getting sneaky. If the average-speed cameras & digital jobs start getting to infestation levels then I may just take my plates off and be done with it. Sorry officer.. some chavs must have nicked them, and i approached the car from the side.. i'll get them replaced right away. (not)
It just encourages the unlicensed, unregistered, and car theives doesnt it... A decent level of warning signs and road engineering could solve a lot of hassle (no more blind bends, etc)
Given that apart from fussing over wobbly wheels, a good 10 mile stretch of the travel home from college wednesday was spent on country roads hanging back from a reasonably rapid line of cars and
not checking the speedo at all for most of the duration apart from towards a tricky corner, and it was the most enjoyable and also safe sensation, I still can't see the benefit in keeping to a rock solid 30mph or whatever. Its a total george bush of a law.
Just a case of playing the waiting game again...
