There’s very few people who want cars totally out of the equation. I live in one of the most bike friendly parts of North America (Plateau in Montreal) and there’s still plenty of car traffic. There are arterial roads where cycling is discouraged, and many local roads without bike lanes but designated one way to discourage through traffic.

Even here, people need deliveries, they need to leave the neighborhood. The issue is the car being the default option, not that it’s an option at all.
