> The article has evidence of modal shift. Car journeys are down, but both subway ridership and foot traffic are up.
In addition to making for a more pleasant environment, it's also worth pointing out that in a dense urban area, cars are pretty terrible in terms of people throughput compared to alternatives. People traveling in cars take up way more space than the same number of people riding buses, subways, bikes, or even walking, and the cars don't have enough extra speed to make up for it (in fact they're probably slower than everything except the pedestrians). This doesn't matter as much in less urban areas where there's plenty of room to spread out and the higher speeds that enables, but in downtown areas cars are realistically a pretty slow way for a bunch of people to get around.
