It was, mainly, a joke.
But if we are going to be serious, I still would love them to buy up VW. TSLA market cap is big enough that they could do it, and they have a corporate environment that is at least semi-receptive to electrification.
Oh, and VW has some very nice factories spread around the world that I'm sure Tesla could retrofit nicely.
Not saying it's the BEST use of capital, but if we are putting our wish list out there, Tesla gobbling up a traditional automaker is on my list. It certainly would get the attention of the traditional automakers and the nay-sayers on Wall ST.
