Elon has always been a slightly clunky presenter, that's part of his charm. But devoting almost the entire presentation to your vehicle being smash proof (here's a video of bullets, here's a guy on a ladder dropping a metal ball) and then casually smashing both windows without much effort is just bizarre.
Why not focus on the utility that this vehicle gives workers? Show a bunch of guys building a movie set and powering a bunch of tools off it. Show it nailing an off road dirt track. Show it driving through a stream. And as I said, show a few of them dragging a Falcon 9 first stage. All of this could have been done with Elon being his attractively awkward self. It was just poorly executed, which is a crying shame for all those that worked so hard on the vehicle.
It's a shame because up to that point I thought he'd been executing really well. There was a great vibe and he had great excitement and energy. After that it felt sort of rote, in a "the show must go on" sort of way. I get the impression that they very much had been practicing throwing steel balls at the truck and had never seen what happened, and were rather in shock that the glass actually broke. Hope Elon tweets about it as soon as they figure out WTH went wrong.
But as mentioned above, I really wish they'd gotten into the logic behind the truck rather than leaving the audience think that the unusual aesthetics were purely some sort of style choice.
