Sorry, but this is BS. Modern electric engines in Tesla Model 3 use high-speed power transistors to precisely modulate the magnetic field. Back in 1920 all you could do was a collector plate with brushes.

The difference is like the difference between carburetor engines and direct fuel injection.

And these are still more efficient than most combustion engines *today*, that's exactly my point.
