Good to hear you on Radio 4's The Today Programme this morning. I have a good example of the revenue-earning motives of the police and safety partnerships. About two years ago, a stretch of the A5 in North Wales was being widened. The otherwise national speed limit (60mph) had been reduced to 30mph with temporary traffic lights. The majority of the work had been done, the new width road was fully open, the new white lines painted, but there were some wall repairs in progress so on occasion the traffic lights remained. But, as the Easter weekend was approaching, the workmen were obviously clearing everything so full two-way working could be allowed over the busy period (I'd been up and down the road several times that week, so had seen the progress).

All bollards were off the road, but the 30mph signs remained. A bend obscured the start of the roadworks area and of course, on the busy Easter Saturday when I drove down at 34mph, I and no doubt hundreds of others were caught by a mobile speed van - they must have had a field day. In reality, the road was safer that day than it had been for the last 50 years before it had been widened. Ironically, at the other other approach to the roadworks since the widening, there has been a bend speed limit of 35mph, which I consider to be too fast and I'm awaiting yet another motorcyclist to be killed.
