I wonder too, if it's true that the person who died in the crash reported the area, what process Tesla followed and .. Any area reported with a problem IMHO should immediately start warning other drivers going in the same area until the issue is resolved, even disabling auto-pilot completely until Tesla's resolved it. I'm sure that would make people safer than the temporary inconveniences they would cause - I'd hope people would take that attitude anyway.
There may not be a solution in sight for making robots deal with badly marked roads for example, but we might be able to just sidestep the problem with better road markings or more conservative handover-to-human protocols in areas with improperly marked roads.
You can go back through Animats comments here and see criticism of the (apparent) approach Tesla is using, for months and months:

This further confirms for me the feeling that autopilot in cars won't become even remotely common for another decade, especially in any parts of the country with poor weather.
