Sorry, pure conjecture on my part. I just know Elon is as close to a Bond villain as it gets, they have released misleading reports for years, their fatal accident ratings are atrocious, Elon fired regulators that oversee his business, Tesla has lied about missing crash data, and there's a fair amount of open lawsuits involving safety (some from whistleblowers).
Just saying accidental acceleration would be an easier pill to swallow if it was any other car brand.
