That is a flawed argument. You are taking a small sample and making an over generalized conclusion. It was one trip that happened to have 1 fail in it. There were other test drives with no fails at all. I could show you a video of a Waymo car failing on just a 5 mile trip but that doesn't mean that Waymo cars fail every 5 miles.
Look, if you want to continue to doubt and be skeptical, that's your prerogative of course. Tesla has given us some concrete evidence that they are making good progress on FSD. We will probably get "feature complete" software by end of this year, if Tesla stays on track with their timeline.
They need to hurry up and catch up because they are still years behind in camera based neural network development and deployment.
