Very impressive... BUT the car was driving itself in ideal conditions, with high visibility in all directions and amidst light traffic. What I'm really hoping to see is a video of the car driving itself in more dangerous situations, such as in the middle of heavy rain or thick fog that limits visibility, or at night on a dangerous stretch of highway with lots of trailer trucks zooming by, or surrounded by tired angry drivers on a major holiday in a popular route with bumper-to-bumper traffic. When self-driving cars can successfully navigate those and other similarly dangerous scenarios, we will know the technology is ready.
