Based on the article, it sounds like the driver is only responsible for changing lanes when all normal lanes are blocked: i.e. a truck is blocking the only lane on a 2 lane road, and the driver has to cross over into oncoming traffic to get around it. While this is disappointing, it's very understandable that they haven't automated this process yet.
