I live in Norway. Growing up, some days in school were reserved for diverse activities. Some of my friends and I decided to bike to the swimming park in the city ~20 miles away. We didn't have to bike on car roads at all to get there, as bike lanes and good side paths lead us the whole way. Being able to get anywhere with a bike at the age of 14 is an amazing level of freedom.
Growing up in the 90s in the usa, movies and tv always showed kids riding around on their bikes and not coming home until dark. Where the hell did they go? To get from the suburbs into town would be 10-20 miles riding on the edge of the highway almost wherever you live. No shoulder, no bike lane, no nothing (I did this to get to work for about a year. it sucked, got hit by a truck twice in that time.)
UK here, not perfect but we did have quite a few paths that either don't allow cars or don't have many so cycling around was pretty easy. Cars make people lazy. Many people I know will drive to avoid an 800m walk.
I could stare at the streets and walkways in a typical netherlands city for hours. I love good brickwork. Sometimes I get on google maps and just digitally walk though places. I don't want to point at amsterdam, because everyone knows amsterdam. Try lelystad, built on land that was underwater not that long ago but reclaimed by modern dutch engineering.
I'd gush about how beautiful their streets are, or I could link a video that does a much better job than I ever could.
