I'm not a nomad but I'm car-free for multiple reasons. I live in Denver with a pretty decent transit system, and I can easily walk to the nearest grocery store. I work remotely so it isn't difficult for me to get by without a car. I also have the option of renting one if there is somewhere I want to go that requires it. It's working out very well for me. However, I think it would be impractical to nomad around the US without a car, especially if you like visiting state and national parks.
