What would actually happen is less suburbs and more cities connected with trains. Distance to the closest city decreases preserving the agricultural productivity, and the proportion of people living in the cities inreases - wasting less energy and time on pointless commutes and increasing opportunities for good education and innovation. How do I know - because that's how European AND American countries developed when there were no cars. BTW in ideal world you of course have cars, but the petrol cost includes all externalities so only people who really HAVE TO - use them daily. Other than that they are used for public transport, medical services, firefighters, etc. The fact that the most popular car in USA (which has <5% farmers) is Ford F-series truck is absolutely insane.
