Will Farage let me drive on the right if I want to?

Whether the 20mph default speed limit in built-up areas is a good thing or a bad thing is obviously a matter of opinion, depending on whether we prioritise reducing casualties or convenience and speed. The statistics show that it has reduced the number and severity of casualties on the roads, although a thorough evaluation might need a few more years to assess whether it is really working as well as it appears to be. On the downside, experience suggests that it has led to an increase in aggressive driving and risky overtaking manoeuvres, especially by those vehicles whose drivers are exempt from the law. I can’t find a definitive definition of exempt categories in the legislation itself, but simple observation over the past year leads me to conclude that it includes taxis, white vans, and BMWs.

Farage told us last week that it is a ‘looney’ policy, and went on in a Q&A session to describe it as being an example of government telling people what is right for them, adding "It is typical of control, control, control". In essence, his view seems to be that it has nothing to do with safety, and that the Welsh Government have introduced it solely with the aim of controlling what people may or may not do. It’s a particularly silly argument – if it applies to the 20mph limit, then it also applies to the 30mph limit, or to any limit set at 40, 50, 60 or 70. All of them control what citizens can and can’t do. Come to that, why should the government control on which side of the road I should drive? All laws set limits on what we can and can’t do, they all ‘control’ us to a greater or lesser extent. The question is – or ought to be – about where we draw the line, and how we balance safety against speed of travel – or, more generally, personal advantage against collective advantage. ‘Not liking something’ is not enough to distinguish between an arbitrary control of behaviour and a sensible safety measure.

Reasoned debate is not, though, what Farage and his ilk want. Their aim is to appeal to people whose minds are already made up, and to strengthen those existing prejudices. Not that reasoned debate would ever help anyway. No-one who has not arrived at a particular view in the first place through a careful and rational study of the evidence is going to be persuaded to a different view by a careful and rational study of that same evidence. And that doesn’t only apply to the question of speed limits. Believing that evidence can and will shift an opinion which was never evidence-based to start with is a mistake which many of us make. Overcoming prejudice and a willingness to disregard mere facts is more of a long term project, which involves teaching critical thinking as a key element of education. There is a reason why Farageists and their fellow travellers are hostile to the idea of an educated populace.
