I was at a cocktail party last night, in the heart of liberal Tesla country (Northern California). One of our friends is a local TV news producer (decides what's news each day, what goes on the air). Someone mentioned my Model 3, and she said, "Aren't you worried about them going out of business? You don't use Autopilot, do you?!" [concerned look on face]
The long and short of it is that the negative narrative about Tesla has become—at least in the short term—the "prevailing wisdom" about Tesla. So a news director wouldn't feel smart running a story about how exciting Tesla is, or great the products are, or about how cool the technology is. Instead, they feel that the responsible thing is to warn people about the bad things that might happen.
If Tesla succeeds, they can still feel like they did the responsible thing by warning people. "Those were valid concerns," they might say.
On the other hand, if they put out a rosy piece about the company or its products and something bad happened, people might feel that the news company misled them. "Where was the press when this was happening?"
Even in California only a tiny fraction of the 40 million people here own a Tesla. If every Tesla ever produced was now located in California, it might crack 1% share of all cars, barely. Having been historically very expensive and linked to climate activism, there's a fairly sturdy contingent of people, even in California, that think of Tesla owners as privileged and holier-than-thou about saving the planet. I was recently talking to a senior executive from Oracle and she said she couldn't bring herself to become "a Tesla person." Make of that what you will.
So if you think about it from their perspective, there's very little reason for a news producer to post a positive piece about Tesla.
