The post is implies, that there is a huge latent demand for cycling in the UK, which will translate into actual cycling if the infrastructure is provided. The truth is that many adults in the UK prefer to drive a car, live in a low-density suburb, and at least accept (if not prefer) a longer commuting distance. They will not cycle, regardless of what infrastructure is provided.
Perhaps some people in this country do still love their suburbs. But most British people fell out of love with identikit low-density suburbs decades ago.
