Btw, an example of this is the interurban network, which linked not only large cities, but small towns across the so called United States. Here's a map of electric railways on 1899 in Massachusetts, which is considerably better than any transit offered today. Interurban at the zenith of their technical development (which coincided with their ridership decline) could go 90mph. It's likely that without state intervention in the form of highway building these would still exist.
