Software with a battery pack (and no headache of a drivetrain).
Luckily for Tesla, most of the other car companies disdain software engineering and see it beneath them and mechanical engineering. My friend had sold his software company to BMW in 2008 and they didn’t even ask him to join BMW. Even more shocking they used the same software for over ten years with NO upgrades and updates.
You are misleaded. VW sees itself as mainly software company now. They don't do engines nor drivetrains, but they do heavy SW. This way they think they can control the technicians.
