Right, yes, that's all very well-intentioned
but as Jacob Rees-Mogg informs us:
"20mph limits are ridiculous. They simply obstruct the flow of traffic. People are in favour of them when they are proposed, and later realise how annoying they are. It's a microcosm of politics generally: opinion polls suggest something would be popular and once you put it into practice it isn't. People should be free to lead their own lives as far as possible without Government interference.”
