Just one chunk from a long and interesting article -

We need radically to restructure our urban mobility systems in ways which will get people out of their cars and make them cycle. Half of the infrastructural change required is underway – the push for a maximum speed limit of 20 mph on residential streets is gaining momentum. But the other half of the key infrastructural change required needs a similar push, and this push should be for very high quality and continuous segregated cycling infrastructure on our biggest and busiest urban roads, the kind of roads on which almost everyone today refuses to cycle.
The task might seem enormous, even impossible. But it’s not. Think about how things change. Our research has made very clear the normality among a large proportion of the population of using a car for short journeys. But this normality has been produced over only the last fifty or sixty years. We used to travel differently, and we will do so again.
