Says a guy who is short on Tesla, but despite that conflict of interest, the video looks real. I mean if he had managed to modify his car firmware to make it less safe just to fake that video, that would also be a huge Tesla safety issue.
If you're anti-Tesla because you didn't think Elon Musk was funny on SNL, or you don't like his haircut, or some other unrelated reason, that's what would be unfair. But you can't write off anyone short on Tesla as inherently biased. Otherwise you'd be writing off all criticism period.
