Car-centric urban planning is hell with kids. You have to load them up into the car for any small trip. You can't walk or bike anywhere because cars make it so dangerous.
My only regret about living in the US is this car hellscape that is so hard to avoid. It's mandated by law, not chosen by the market.
Chicago has (recently?) put a lot of focus on their bike infrastructure (protected bike lanes, bike signals, bike only paths, etc) and it seems pretty widely used.
I'm certainly not opposed. But my observation in the relatively nearby city when I go in and sit on the sidewalk at a restaurant is that the fairly new protected bike lanes have a fairly terrifying combination of transportation modes (bikes, ebikes, things that I guess are ebikes but look almost like small motorbikes, escooters, and pedestrians crossing). And then, because they're in a bike lane, many seem to assume the signal at the next street doesn't apply to them.
Not sure of the best answer.
