Savage Geese, The Autopian, The Drive, Road & Track, and Motor Trend all individually reported on some or all of these issues. The tonneau cover leaks became a meme that people reposted on places like TikTok and Instagram. It's not those terminally online, it's that in the first year of the Cybertruck's release a bunch of outlets were documenting it because it brings in readers.
As someone who doesn’t own a car, every single time the cyber truck shows up 50-90% of the info is about these issues. Why would you trust individuals who already bought one more than auto reviewers?
