I live in Copenhagen which is very comparable to Amsterdam. We have great public transport with busses, trains and metro so it’s easy to get around even if you are not biking. There’s space in all of these for prams and wheelchairs. More importantly, obviously people can still take their cars. These cities are not car free utopias. I have lived here for more than 20 years and I’m in my 40s. I’ve never owned a car nor do I miss having one, but it’s not uncommon to own a car and a lot of carowners will still frequently bike or take public transport as it’s just easier and faster.
