WHY is it that, the moment you get a 50mph speed limit sign crop up, some drivers will hit the brakes and will not travel any faster. Yet that very same driver will not see or stick to any other speed limits, be it 20, 30, 40, 60 or the national speed limit of 70 on a motorway?

Why are these silly 50 speed limits so special? The police speed camera vans love them but have no idea that there are other speed limits around.

Just think if one of them was to sit on the M40, like the police of yesteryear, or even try a 30 limit in say Camp Road, Upper Heyford, or Banbury Road in Oxford. But no, they only know the 50mph roads, like the A44 at Yarnton, and this goes for most of the so-called ‘drivers’ that drive around, going about their business, just sticking to this silly 50mph speed limit.

Yet when they enter a 30 limit, their speed will be 35+mph and, knowing that the chance of getting caught speeding by a police car or the camera van are so slim, they think ‘what the heck, it’s not my neighbourhood’, and so carry on in excess of the 30 limit. This needs to stop. If these camera vans are to do the job of enforcing the speed limit properly and not the half-hearted job they do, then make sure they do so on all roads and not just the money-grabbing 50 limits in and around the county. Or better still, Oxfordshire County Council should get rid of these silly 50mph roads, reinstate the national speed limit for that type of road and spend the money on better things, like better cycle tracks in and around this lovely county we have. Why doesn’t some of this money that the camera vans make go to funding more cycle ways to connect more of the towns in this county?
