It’s also only feasible if actions like this congestion charge are taken to tilt the scales. Most people would not use public transit if they could avoid it. When there is enough road infrastructure to match the density, private transit is preferred because you can drive directly to your destination, not have public safety issues like on the subway, haul cargo, and do it all quickly. The only way to make public transit attractive is to artificially and maliciously mismanage things to make driving cars slow and expensive. Which frankly is hostile towards people.
