I meant critical component, not seat buttons. People are getting too involved in this.

Nobody gives a damn about the infotainment or door knobs.. it's delegated to one supplier just like a phone charger or any secondary part.

The car mechanics, engine, battery and control units are what I was mostly thinking about.

If Musk keeps on going their EVs car body will be two cast parts, so in terms of supply chain management the complexity is gone into the manufacturing process.

A Tesla has 40+ Electronic Control Units. Even if you just look at that, it's way more complex than a phone. Sure, the powertrain has fewer parts in an EV, but everything else is still the same as a regular car, and all of that stuff is a lot of stuff.
