That's part of the story (though, why did Tesla ship a luxury truck with such trash tires?). Weight is a actually good thing in light snow. If you have low traction, you can actually add weight to the truck bed to get better traction. Folks in my neck the woods put sandbags and stuff in their beds to do exactly that.
Keep your eyes on what the tires are doing in the video. See how they're rolling at all the wrong times, and then locking up at all the wrong times? That's an electronic system failing, that's probably the Automatic Traction Control, and evidently it doesn't know what the fuck to do with snow.
I know him!!! He featured heavily in that one Walter Isaacson biography, The Codebreaker. About Dr. Doudna of course.
Did he get his PHD? Well, good on him. I see China has a better anti-recidivism program than the USA has. Last I heard, he was doing hard time in Chinese prison for mad scientist stuff.
