I finally caught my Tesla ignoring a voice command it clearly heard and understood. It properly shows the command in the text box, then does nothing with it. It does this when it has no connectivity, but when it has no connectivity, nothing shows up in the text box. This is the first time I have been able to catch it where it clearly heard me, clearly understood what I said, then completely ignored me.
Though I’d want more hard buttons across the board, at a minimum I’d argue it needs to be a real button for any safety sensitive activity. Gear selection, steering, acceleration and braking, wipers, defrost/defog, turn signals, lights, etc.
