If you want to be fair, compare American cities with European cities. In Barcelona or the center of Copenhagen, there are not free parking spaces. And I can assure you that there are not the traffic issues that you are mentioning in your comment... It's quite on the contrary, actually.

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" :-)
I mean, flying a helicopter around the city sounds like great fun but that doesn't mean everyone else should be forced to build places for me to store said helicopter.
Everyone suffers because of it, whether they are actively utilising the roads or not - because the people who are using the roads are their customers/staff/suppliers/whatever. If half of my staff can't get to work on time, my business suffers. If my customers can't get to me, or don't feel the time investment is worth it (I've done 3km in 3 hours in Dhaka), my business suffers.

Barcelona makes it into spot #92, actually. It's really not that small, the metro area is a bit over 5 million people.

Barcelona is not an order of magnitude smaller than any US city, unless you can think of a city in the states with a metro pop of 50 million.
