This is a series of good points. Near where I live (Australia), we had some roadworks on the freeway, causing the lanes to be temporarily moved. The "new" lines where yellow, instead of the normal white, and much harder to see. Further, this happened several times, so you just followed the "most yellow" line, and hoped that nobody rammed into the side of you. If, instead, we have a set of local sensors setup that identified the new "safe" path, an automated car could easily go through this new section. As marked, however, it would be very dangerous to rely on an automated driver.
