I’d say it’s more the influence of the industrialist class and the oil barons tbh.
Like for example, modern medicine is also extremely based on petroleum and it’s extremely dependent on the oil industry. This is a manufactured end caused by the oil barons (you can google “How Big Oil Conquered The World James Corbett” for more details).
But for transport, the early automobile corporations literally bought the streetcars in all the major cities and just dismantled them. They lobbied to stop existing subway projects, and all future projects that came to be for rail etc. For a modern example see Elon Musk and his Hyperloop almost killing California’s high-speed rail project.
All in all, the US has been controlled by old-money, big industrialists and Wall Street since forever. If you want to know why something happens, just follow the money. Everything has happened according to their interests.
