Nobody is saying that cars should be completely banned. Cycling should be encouraged. Governments should sponsor buying bikes, build loads of GOOD cycling infrastructure (look at the Netherlands for examples for gods sake, cycling infrastructure in the Americas is a dangerous joke), make owning and using a car more expensive, make it easier to arrive to destinations by bike than by car. Invest heavily in public transportation.
The US could have had all that the Netherlands has now but it doesn’t. It has huge and ugly cities that can only be used by car owners. If you don’t own a car you’re a second class citizen. You will mill out on good jobs. All that is insane to me. I never NEEDED a car. I can have one, but bikes are easier 100% of the time in sub 15 mile radius.
