Let's assume everyone takes a car instead of public transport. Where do you think people will be parking in cities like New York or London?

There is no way cars are the solution to this.

Where would people park in economic hubs of Boston, DC, Philadephia, San Francisco, Seattle, Miami, etc...

I couldn't find a parking spot in Palo Alto, CA... and that's not a densly populated area.
