Clearly not ready for unattended driving
I don't know on which roads these tests were conducted, but clearly on the roads in Europe the self driving fails every other change of road. It is odd to measure the distance, since driving along a perfectly straight line is possible for hundreds of miles. But clearly it's the change of the situation which is an issue for the autonomous driving. Easy tasks like identifying the markings on the road go bad in 6 out of 10 times. Identifying a vehicle which is 50 meters far upfront waiting to turn left, triggers a steep deceleration although the car is on a different lane.
Whatever they'd like to make you think, autonomous driving is as far away as nuclear fusion ...
