We cannot even so much as consider dedicating less of the most valuable land (downtown city land) to cars. It is unthinkable, impossible, and bad for me, somebody who drives from the suburbs and expects to be totally accommodated at the expense of people who live here.
No parking altogether discourages car ownership. Unfair to the people who live there to change it aspirationally, but if you provide other transportation options that are better than driving, then you don’t need it.
