Some guy in a cupboard then counts the lines crossed in that time and calculates the speed (he's probably not bright enough to calculate the speed, he just knows how many lines is over the limit).
no... the radar is the thing that calculates the speed!!!!! The lines are there to back up disputes, and as a quick reference to mis-triggers

each long line on the Photo indicates 5mph the 4 small lines inbetween the long ones obviously indicate 1mph
thats how Im guessing AK was 9mph over the limit in his pic?

The lines are counted in every single one of they gatso photos as far as I'm led to believe.

ok.... MAYBE eyeballed... but as a sanity check to the measured figure from the radar
MattK - No.... lines arent always the same distance. Some are 5ft, and some 2m.

no, its a kit car (lotus 7 type)
He just over took our car, going faster than us... to say i'm mildly confused as to the ticket is an understatment.
Car was flashed at 70mph.... in a 70mph... with a trailer (so limit is 60)

also gatso's are activated by satellite iirc. it isn't the camera that detects your speeding, its actually a satellite that relays to the camera to take a pic. a manual operator then has to sit down with all the tape when he receives it counting how many white lines have been crossed doing distance/time calculations .
looking at the artistic picture supplied you should be fine  ordinarily the first flash is closer to the start of the lines than you were, especially at 70 because within that half a second between flashes you'll be surprised at how far you actually travel.
im sure you'll be fine
shut up
Read up on them.... they radar based, and the white lines are just a back up to check/prove
radar thats the one. why i put satellite i do not know i should imagine it would be quite difficult and there would be quite a few collisions having satellites up there for speed cameras. i do stand corrected

If its a 70limit dont forget you get your 10% so you can in theroy cain it throught at 77mph if you want to take the risk but at 71-72 they cant do much
