I have a question someone may be able to answer.
Yesterday I drove through a Gatso speed camera, one I pass at least once a week, and it flashed me. I was driving at the limit posted, 50 mph, and there was no other vehicles in my carriageway. On examining the dash cam video footage it shows my GPS speed as 49 mph, Close examination of the video frames show that when the first flash went off I was at least 20 feet short of the lines in the road. I was astride the lines when the second flash occurred. Does this mean it was not me that triggered the camera? There was a Transit van that appears to be travelling fast in the opposite carriageway, but it doesn't trip the camera on that side. Why I say it was travelling fast was it was sailing past the cars in lane 1 and most drivers slow to just below the limit to pass the cameras. This is on a two lane motorway.
As I have driven for 50+ years, without so much as a parking ticket, a speeding ticket would be a Christmas present I wouldn't enjoy receiving!
