In legalese it's true... the tweet was "Just started Tesla Robotaxi drives in Austin with no safety monitor in the car.".

An analogy would be if a husband came home from a job trip in Denver and his wife accused him of cheating, and his response is "I wasn't cheating on you in Denver!", because he cheated on her in Boulder.

"No safety monitor in the car". Somehow the image of Mr. Bean driving his car from an armchair mounted on top of it comes to mind: https://www.youtube.com/watch?v=LVSLLWXdKV0
