&gt;&gt; ... Invest in public transportation.<p>&gt;&gt; ... The US is a country where it&#x27;s very difficult to live without a car, except in certain major cities.<p>In order to do this, we need to rethink how we design cities. Right now, unless, as you point out, you live in a major city, it just isn&#x27;t well laid out for public transportation. No amount of retrofitting is going to help. City planners need to take public transportation into account when they issue new building permits, etc. They need to encourage business to build closer so people can use public transport. Here in the south, thought needs to be put into thunderstorms. We can have afternoon thunderstorms with 50MPH winds and deadly lightning pop up very quickly. You can&#x27;t have people out waiting on public transport in that mess.
