I myself have been car-free for about a year now. I own a Lectric XP ebike, and if you can learn to ride on the road and plan your route, it's not too hard to commute via ebike, even in the states. Also helps is that there is a long bike trail that run throughout the metro area. In addition, the bus service in my city is very underrated and actually goes to places that people care about. So yeah, if you can operate an ebike, you can live car free.
