Surely, this question is targeted at USA/North Americans. The average commute is beyond biking distance. The average suburb is sprawled beyond biking convenience. So, exactly to your point, people reliant upon cars largely don’t see the benefit potential of bike lanes. You can point to tight older cities like NYC or Chicago, but, surprise, the cars in the city traffic aren’t fromthe city. They drove in form the surrounding neighborhoods to their jobs.

I biked for 2 years when I happened to get a career job in the town I lived. It made sense because I could cut through a park and skip the traffic light bottleneck. The 2nd closest career job I’ve ever had was 17 miles. The furthest was 65 miles.
