Can we have some signs to remind people that 30mph is a speed limit to be attained, not feared!
There seems to be a few people who think trundling from Offerton to Marple at 25mph on the speedometer (nearer 22mph in reality) is a good idea. Trust me, it's not. It bunches cars up (anyone done fluid dynamics at any stage in their life?) making it more difficult for drivers in side streets to pull out safely; it frustrates others and whether it's an impetuous youth who doesn't have the experience or James Bond in his BMW, some (and I'm not endorsing this), will be tempted to overtake in order to progress at a true 30mph (maybe 33mph on your speedo folks) after the mobile instruction is passed; and it increases fuel consumption - bad for the environment but good for the country's coffers I suppose.....
If you're not a good enough driver to hold a steady 30mph, hand in your license!
And before anyone starts lambasting me for encouraging speed, I'm not. The posted speed limit is 30mph, and the Highway Code is full of direction to keep to the posted speed limit, and directions not to needlessly interfere with, or impede, the flow of traffic!
