Did An Angry Tesla Employee Send Out This Weird Tesla Model 3 Mockup?

Last night, we got a very interesting email. It's the sort of mail that, as a car journalist, you're always hoping you'll get, if I'm honest. It was from an anonymous person claiming, with evidence, to be a Tesla employee. The person wasn't happy and they sent what they claimed to be was an upcoming Tesla crossover. And that's when things started to get very strange.
