This is just so wrong. But it gives me an idea. I'll get me one of those police driver under instruction notices - I might be able to get away with more!
There is a difference between reckless driving and fast driving. If you have good anticipation, full control of your car, a lot of experience which helps with the unexpected and you don't take chances you are a good driver. However if you take chances and fail to take into account the ever changing road conditions you fall into the reckless category. (Tiredness can move a driver from good to reckless!)
I think I am right in saying that the police still have to obey all of the traffic laws with the exeception of speed when the blue light is on (they still have to avoid dangerous driving) they can also ingore traffic signals and lane controls with the blue light. (I'm sure HDi has looked this one up at some point?)
