The solution to this problem, at least for the foreseeable future, is to have the autopilot only active when the car is on a certified autonomous road. This would have to be a legal definition, in which road construction would de-certify that road section, and the certification continuously updated via the autonomous cars themselves. As soon as cars start seeing degraded conditions they update a central database, which alerts other cars to switch to manual mode well before entering that road section.
