I visit Amsterdam periodically for business. In the city center, where there are very few cars, there is far more noise, smells, and crowds than I would care to live with everyday.
Density of people brings those three annoyances, cars or no cars.
Not even that. I live a little outside the centre of Amsterdam (I could walk to De Wallen in probably 30 minutes comfortably.) Most residents don't go into the centre because it's a mass of tourists who haven't learnt how to walk outside of bike lanes. In my neighbourhood, there still aren't that many cars, the footpaths and bike paths are wider, and it's generally calm and quiet, and I sit on a moderately busy road, a small street off it will be much quieter still. There're a few cafes that I go to that are a bit more central, but it's still mostly outside the really busy area.
I think most people's - even a lot of Dutch people's - experience is getting off at Centraal and walking to some bar in the centre, or going through the shopping areas, and then extrapolating that to everywhere else in the city so all they imagine is that busyness.
I have. Most of them seem to be car-centric, to the point where many of my work colleagues living there don’t even have an OV card (and were shocked when I said I had one as a tourist).
Maybe you should move to the moon then, because you either have density that allows you to enjoy nice services and comforts or you live in the boonies where you need a car and perpetuate the inefficient consumption of resources.
Those are caused mainly by cars. Take away the cars and there’s a lot more space and fresh air for everyone.
