Here in North America, we have solved the problem of too slow driving with state and Federal laws. It's legal on divided highways to pass in the right lanes if the left lanes are blocked. Similarly, on 2 lane roads, state laws require you to pull over at the first opportunity and let traffic pass you if more than 3 or 4 vehicles are behind.
It seems to work well, with minimum congestion on the open road. Why these policies haven't been implemented in UK is beyond me.
Very good idea.
I regularly see drivers pootling along at 30mph in a 60mph limit with half a mile of traffic behind them. I was stuck behind one yesterday in fact.
