Almost hitting pedestrian is a big stretch. Car had enough time to stop before he took hold. He probably just picked up the wheel because he didn't want the car going that way.
It's barely a stretch. The car veers pretty significantly. The driver and the pedestrian both notice this and wave as a 'sorry'. The car may have stopped, of course we won't ever know, but it's absolutely wrong to say that it was just the wrong direction - again, both the driver and pedestrian acknowledge the aggressive turn.
Car wasn't at a very high speed and if breaks are working normally it would have a lot of time to break before hitting the person. Almost hitting a pedestrian is a big stretch of a title, we don't really know what the car was going to do. Probably there's some logs on the car that will tell Tesla if the car would stop or not, but for the viewer of the video we don't really know.
