Hmm, presumably SPECS only retains vehicle data if the calculated speed is above the prosecution threshold? And presumably the threshold in this case is set to something like 45+?
Would they not set the prosecution threshold much lower for SPECS cameras? As car speedos should be reading a little high, and a momentary lapse of concentration resulting in a slightly higher speed for a short period won't have much impact on the average speed, everyone who attempts to keep their indicated speed to 40 ought to have an average below 40. I always assumed (and I'm willing to admit possibly totally incorrectly) that there would be close to zero tolerance with SPECS cameras, so I aim to never let my speedo indicate higher than the speed limit while driving through a SPECS section.
I think that these 40mph limits on motorways are totally out of control, though. Even with the roadworks, these roads are safer than 60mph limit roads I drive on every day. And don't get me started on the 20mph limits that we now have on near enough every single road in the town I live in, even what I would class as "main" roads, I suppose we'll be getting SPECS cameras on those as well at some point.
