Electric cars are of much simpler construction (and repair); the limitation right now is battery capacity, which directly reflects in driveable range. When batteries downsize and up power, it will be a very different story.
Building them is no great feat, the motor has over a hundred years of history and other components are widely available. The price point isn’t there yet.
I will “subsidize” my own electric car; paying taxes so DeCaprio can drive a subsidized electric car is crony-cRapitcalism.
