Lets say we are enterprising entrepreneurs, and want to make a new car company. What would be the easiest path. Winding an electric motor, providing the power source(battery) and connecting to differential and controlling the output. Or developing an internal combustion engine and the associated hardware and coupling that output through the drivetrain, along with factoring in all the regulation.

Seems they took the easy way out. And all the regulation is on the initial power supplier. All while getting government subsidies.

There is the true intelligence.

And its not rocket science ......pun intended.
