No bike friendly city, and very few advocates for them, are suggesting to ban motor vehicles entirely. Rather, we can structure infrastrucrue to serve both, instead of just cars.

A 4 lane stroad can be turned into a two lane, limited access road with protected, separated bike lane and a median. This actually improves auto throughput, travel times, and emissions.

A 2 lane residential street can have restricted parking, narrower right of way, and wide rsidewalks. This naturally slows cars, making shared right of way safer for all.

A pedestrian zone can have moveable bollards, so that deliveries and mobility services can still access, whil keeping the street safe for people.

In all these cases, its not about bulldozing buildings, its about changing the way we use existing land.
