If your goal is to have an significant impact on climate change, you'd more bang for your buck and just as likely a chance of banning red meat, especially with electric car ownership on the rise.

I've commuted by bike and public transportation for a number of years and I'd never want to ban vehicle ownership. A more workable solution would be to make driving tests less of a joke or to make dense areas of city centers car free zones. American cities are just too large and often times people drive without a destination in mind, like my Sunday drives down the California Public Highway along the beach.
