Here's the source. There were actual-court cases which found that oil and car manufacturers conspired to monopolize and convert local public transit to buses from rail.
"Between 1938 and 1950, National City Lines and its subsidiaries, American City Lines and Pacific City Lines—with investment from GM, Firestone Tire, Standard Oil of California (through a subsidiary), Federal Engineering, Phillips Petroleum, and Mack Trucks—gained control of additional transit systems in about 25 cities.[a] Systems included St. Louis, Baltimore, Los Angeles, and Oakland. NCL often converted streetcars to bus operations in that period, although electric traction was preserved or expanded in some locations. Other systems, such as San Diego's, were converted by outgrowths of the City Lines. Most of the companies involved were convicted in 1949 of conspiracy to monopolize interstate commerce in the sale of buses, fuel, and supplies to NCL subsidiaries, but were acquitted of conspiring to monopolize the transit industry."
This history also plays a large role in "Who Framed Roger Rabbit," as a bit of fun bonus lore...
Local public transit in the US is a very different beast to getting across the country.
Manhattan may have high population density, and the public transit that goes with it; but building passenger rail thousands of miles to the other side of a sparsely populated continent just doesn’t add up in the same way.
No, but the two feed into each other. Intercity rail loses most of its advantages if you have to hire a car at the destination.
> Also I'd argue street cars are way worse than busses which have route flexibility.
They're better for that very reason. You can move somewhere with a decent commute and know that the streetcar isn't going to disappear at the stroke of a pen.
I know that you were talking about individual commutes here. The city of Oslo, Norway was considering having a shared trunk in one corner, where the metro, the streetcar, and the intercity rail all shared a stretch of track. I believe it was to make efficient use of existing right-of-way. I think that there were problems due to electrification (750 V vs 15 kV) and other political problems.
There is a different section in Oslo where the streetcar and metro share a stretch of track using a clever interlocking.
