This is really neat, but the question that I always have regarding these self-driving vehicles is how they perform in bad weather. More specifically, snow. Humans often have a hard time navigating in snow when lane markings are covered and snow seems to introduce a lot of glare into cameras, not to mention the possibility of covering important car sensors that may need to "see" the road in other non-visual ways. I'd love to see how a Tesla handles that scenario. Still though, this is a pretty amazing thing to see a car completely drive itself to a destination and park without any human input.
There was that one instance in the video above where the car encountered some people walking on the road and braked hard (which I don't think a human would have necessarily done), but other than that, this was a near-perfect drive.
