If we wanted cheap cars, there needs to be demand to justify building giga factories of EVs.
There just wasnt sufficient consumer demand to justify the giga factory investments
China CAN generate demand for EVs because they have the political ability to
1) force gas restricted cars to only drive on certain days of the week
2) create a brutal lottery to get a license plate to legally drive a gas car
3) provide a bunch of subsidies
The US has only done option 3.
Out govt system literally doesnt have the political will to do these brutal but effective policy changes
