Waymo does about 450,000 trips a week across five cities in the United States, and everyone’s really excited about that - yet New York's bike-share scheme does around the same number of trips every three days.

As The Economist says, “a new disruptive transport technology is rapidly changing cities across the rich world. It is highly energy-efficient, costs almost nothing, reduces congestion and pollution, and obviates the need for huge car parks. Yet it is not the self-driving electric car, as tech moguls and car industry executives imagined. Rather, it is the humble bicycle.”

In London, cyclists now outnumber cars in the financial district by two to one. In Paris, they outnumber motorists across the whole city.
