Tesla engineers don't just work on in-vehicle code though. The servers and systems needed to implement Tesla's telemetry and software updates would be in the same ballpark of expertise, albeit with much less scale and different requirements than Twitter.
But Musk got started by confounding x.com/PayPal, which does have very similar engineering needs as Twitter. It's not like Musk is a newbie to this stuff, people pretending that he's clueless in this domain just want to feel schadenfreude.
We've gotten quite a few public comments from Musk on what he plans to do with Twitter, and they indicate total cluelessness from a product and engineering point of view. There's nothing to indicate an appreciation for the unique challenges Twitter has in balancing free expression with appeal for advertisers (or even that these needs might be in conflict), or even on the subtleties in what free speech even means for Twitter. The acquisition seems motivated by politics and impulsiveness rather than any coherent vision for the product.
A rocketing share heals a lot of wounds. His abusive management practices might fly at Tesla, or his vision oriented startups. There's ample room for doubt his tactics will get results on a turnaround job like Twitter.

Oracle on IBM big iron is a pragmatic (but expensive) way to achieve a highly vertically scalable database platform. Not trendy at all but also not a bad technology position to be in, even now.
