BBC always seems to add commentary where there is no need for commentary. It's like they are trying to stir up controversy just to sell people on the stories. Personally, I don't think there's anything boring about a car driving itself. The fact that it is so safe, is actually really exciting. If it is proved that these cars are better, safer drivers than humans that is something really exciting. Can you imagine human driving being illegal in 20 years because it's so unsafe? How's that for excitement. There's no reason for BBC to try so hard to appeal to our emotion. The story is great in and of itself.
