Most policies have trade-offs, costs as well as benefits. This will too, in terms of individual inconveniences. But the gains are huge. Cycle lanes are much more efficient than roads, moving roughly five times as many people per square metre per second as the main carriageway. Cycle lanes look empty because everyone moves through them so fast. And that’s in London, where the infrastructure is only OK: in Copenhagen it’s eight times. And reducing car traffic increases, rather than decreases, footfall in local businesses. All this is before we even mention health improvements from a more active populace, and the sheer *much nicerness* of a town with fewer cars.

This should be the sort of thing that a small-c conservative approves of, I think. Improving local communities, protecting children, making town centres accessible and streets safe. So it is nice to see a Conservative government – one that I don’t think of as especially “conservative” — doing it. Johnson’s time as mayor of London was not brilliant, but he did improve cycling infrastructure; he seems to genuinely care about cycling and pushed it through at some political cost. Andrew Gilligan, his transport adviser, is a cycling obsessive too – he turns up at all sorts of cycling pressure groups in Oxford.

It’s only a fraction of what gets spent on roads, or what will be spent on HS2. But it’s real money spent on a hugely cost-effective, hugely beneficial thing. Johnson may yet turn out to be a terrible prime minister, but he’s doing something good, and assuming it eventually materialises, he should be praised for it.
