Perhaps you should read some history. IIRC, at some point, car companies bought up public transit infrastructure and shut it down because less public transit was good for sales.
Friend, I am aware of the "streetcar conspiracy". I am also aware that streetcars died out for reasons well beyond conspiracy. I am further aware of many areas where cars are very useful that never had streetcar systems to be destroyed by GM.
Sorry to have made assumptions. My understanding is that there was no pre-existing infrastructure suitable to cars. The dirt and cobblestone roads that existed were inadequate, to put it nicely. I have read up a good bit on such things and drawn a very different conclusion from you.
In the US, personally owned vehicles are critical for sprawling suburbs and rural life. It is a big country with low density. Cars should not be necessary in the big city. Those that are designed well make it possible to live without a car. In much of America, it is quite challenging to live without a car. This is partly due to choices we have made, not because it had to be that way.
