Thanks for checking this out! To answer a few questions that have been asked:
This video actually was indeed shot the first time we put the whole system together. Of course there were other runs, both demonstrating the alternative approaches and before we had everything working properly, that didn't succeed, but the final system was pretty reliable as autonomous driving goes. That said, we'd want to test this quite a bit more before I'd be willing to lie down where those cones are, and a big issue here is that the maneuver does shred through tires pretty quickly and is pretty tough on the car in general
Second, I certainly wouldn't argue that what we're doing here rivals the very best human drivers (the claim we're making is just that this is one of the more challenging _autonomous_ maneuvers that has been demonstrated). The best humans are certainly able to drive incredibly impressive stunts, and we only claim to be making progress towards this level of ability. However, it's worth noting that this particular maneuver is probably one that _most_ people would have trouble with (I know I certainly can't do it!).
Let me know if there are any other questions, and I'll do my best to clarify.
