Perhaps they know something we don’t.
I mean, if internal combustion engines are RAPIDLY outlawed faster than the other manufacturers are able to complete, and those companies go out of business, and Tesla buys them... then Tesla would prove to be massively undervalued. As more and more people put their money on that, it becomes less of an insane possibility and more of a certainty.
I mean, why doesn’t Tesla buy the 2nd, 3rd, 4th, and 5th largest US manufacturers?
