This NOT a reason he hasn’t invested in Tesla. Makes no sense. If this was an issue, why would he have invested in BYD?Buffett owns a lot of car dealerships too.
There's a reason he hasn't invested in Tesla. They're success degrades a lot of his businesses: Oil, insurance, car dealerships, utilities, even trains (autonomous Semis). Literally the opposite of Tesla.
Buffett is a cold-blooded shark who invests in companies that meet his threshold for likelihood of making him money. He doesn’t care much what business they’re in, except to the degree he thinks that sector is solid.
You can argue about the metrics etc he uses to make those decisions, but you can’t argue with the results.
