Honestly it feels like when a city/area gets dense enough people naturally stop using cats because it just isn’t practical. Most trips in SF are faster on a bicycle than by car, for example.
Then when that happens, it’s easy to refactor architecture to be more in line with what people are doing already.
You'd think so but with the anemic enforcement we have in the US this often isn't the case. Who cares if all the parking spots are taken up when you can just double park in a lane and nobody will do anything about it. When you can speed up the shoulder and skip a few traffic jams with no consequences, why not? Red light running has increased multi-fold since the start of the pandemic. In a lot of busy American cities you'll notice that the lack of enforcement on bad driver behavior means that drivers will bend as many rules possible to make their mode convenient for them. It's an inherent dynamic in car centrism here.
I’ve only lived in SF and Ljubljana so can’t speak of other cities, but in both of those we simply ran out of room. Even if you break all the rules, there’s more cars than space and a walk/bicycle/skateboard/scooter becomes the faster mode of transport unless the city decides to demolish hundreds of buildings to make more room.
I also like how most of Paris has sidewalks lined with bollards so you can’t park there even if you wanted to. Although I always end up running into them as a pedestrian … they hit right at crotch level lol
Careful to draw conclusions from SF it’s just about the only place in the US with decent weather year round in the US. Most the rest is baking hot or incredibly wet (or both) in the summer, and if they aren’t they likely have several months of snow in the winter. Some places even manage both.
I also said Ljubljana, a place that regularly hits -15C and +39C in the same year. This does not stop people from biking and walking everywhere year round. It is also built on a swamp so a summer day with 35C and 80% humidity is not uncommon.
Ok a lot less biking in winter, but always lots of walking.
Yeah, my town spends a month or two a year at 40c and 90% humanity. That’s a whole nother level. Like, 99 seconds just standing outside will have you covered in sweat, but the sweat can’t actually evaporate because of how humid it is.
Literally so hot the elderly and otherwise vulnerable are frequently told not to go outside at all in summer. Heat emergencies are a thing.
Then when that happens, it’s easy to refactor architecture to be more in line with what people are doing already.
