Agreed it wasn't close, but it's still not the kind of behavior you'd want to see in a robot car. If I were a passenger in a car where a human driver did this, I would wonder if they were impaired, and I would no longer trust their driving abilities. Tesla's whole selling point is that a) autonomous cars are safer than human drivers b) we are almost there. This clip shows both claims are questionable at the moment.
I wasn't close because the driver was paying absurdly close attention. We can't say if it would have been close or not, but there's certainly no hint the car had a handle on the situation, and it's clear to see it was making some kind of mistake, even if possible a non-fatal one.
