Your're right, I am looking at it through a self-centered perspective. But I think a lot of people would do the same. If you banned cars, considering how long it takes for decent public transportation to roll out in the US, you would be incentivizing people to live elsewhere. My job and work location are fixed so the only option would be to move out of the city or suffer through a miserable commute. I guess people like me would suffer and those that spend all or most of their time inside city limits would benefit.
