If only there were some sort of solution to cars clogging the road. Instead of one person in one car, we could (somehow, I haven't solved this part of the problem yet) have multiple people in a single, larger vehicle, and that single vehicle could go nearby to the places people need to go to, and they could walk from there to their destination. It's totally radical, I know, and could never work, definitely wouldn't be working in many other places in the world. I'm not sure what we'd call this transportation option, but I'd have it open to the public so that everyone could use this to get around the city. Note that it needs to be a city to have the density to support such a "transportation for the public" option, which involves, you guessed it, building denser housing.
