Call me crazy but I wonder if the windows breaking during the demo was actually on purpose, a Trumpian intentionality. There were a lot of headlines about the truck, such as: TESLA TRUCK'S 'UNBREAKABLE' WINDOWS SHATTER DURING DEMO, etc. And people think, Tesla has an unbreakable truck? Lemme check that out...
Trump does this consistently: he'll misspell a tweet or quote a fact slightly wrong and the media jumps on him, replaying his error over and over, meanwhile the substance of his message gets out.
