A very interesting demonstration, I am impressed by the self driving ability of this vehicle. I would not be comfortable to sit in the back seat though.
Another little hiccough was at 3:43 when it stopped, holding up traffic visible in its side rear mirror, because a cyclist was approaching on the opposite side of the road. And there wasn’t even a floating plastic bag anywhere to be seen.
Unfortunately, needlessly coming to a complete stop, under many non-dangerous situations, is what autonomous vehicles will be programmed to do, and this will cause dangerous situations. This may be programmed for safety, but it will result in infuriating drivers behind the vehicle who may dangerously overtake just to get away from the unintelligent vehicle that seems to jump at shadows.
The vehicle also seems to let other vehicles slip in front of it; there was a point when it left a big gap at an intersection and a van pulled in front—that could be good to exploit when in traffic.
