Well if you want to compare that way to the cities mentioned in the list, the only appropriate comparisons in Europe are London and Paris which definitely have parking, traffic and pollution issues (or had till they started banning vehicles in the center of the cities). Paris even considered banning diesel altogether contrary to the rest of Europe.

Barcelona and Copenhagen arr about an order of magnitude smaller and likely don't even make it into the top 100 cities. In India in casual conversations we would call places with such populations "small towns" :-)
