Agreed. Parts* & Service are two giant profit centers that take a big hit with EVs, which is one of the reasons dealers have been so resistant to selling them for years now. The actual manufacturing doesn't get a whole lot easier, though, which is one of the reasons there have been so many EV startup failures.

*Note: Parts here means only powertrain parts. Tesla, for example, is notorious for having massive delays in repair parts availability for things like doors, trim, and windows.
