The video was too edited for me to have confidence. There was a moment at about 2:05 where I was interested to see how it handled the termination and merging of the lane -- but then we cut away before that happened. Or at 1:30 when there's no big sign post in the median, and then switching to left-rear camera, there we pass one. It's a nice narrative on the future, but it's far from proof of comprehensive functionality.
