What you perceive as emotional venting I think is actually frustration that we are again seeing a media darling company making grandiose claims about its products while the experts on places like HN insist that those claims are dangerously exceeding its true capabilities. A person died as a direct result of Tesla's insistence that they can call it an autopilot/self driving car while knowing full well that it was not designed to avoid stationary objects in the roadway. Press F to pay respects.
