And remember, that a bike lane doesn't have to just be human-powered bikes: it could be e-scooters, e-bikes or perhaps even microcars.
Lots of people want to bike or would appreciate it once they get used to it, but often the infrastructure simply isn't there. If you build good bike infrastructure (nut just the occasional bike path, but a network of them), it will be used, and will remove a lot of strain from the car infrastructure.
I don't think many people want to ride around short distances downtown in a car, hunting for parking spaces at both ends. I really don't like the idea of forcing municipalities to spend tax dollars retrofitting cities for cars. It's quite literally ripping apart the streets to satisfy 5-10% of the population. No thank you.
Do you live in a US city centre? Or do you live in the suburbs, miles out, and want the privilege of driving your large vehicle directly into those city centres when you want to cosplay as an urbanite? I don't know many folks who live in downtowns in US cities who want to drive a personal vehicle around everywhere they go; it's inefficient, expensive, and stressful.
