When I think of the situations that occur in everyday traffic and how people behave there, completely without google being involved, I am absolutely not surprised at the level of carelessness that radiates from such events.
Though it could also be my lower trust in services like google maps because I have a deeper knowledge of the technology behind it than most people. There may be people who think of google maps as some kind of authority that has proven to not be wrong at any time...
If google had enough information and time to correct such map errors and did not out of neglect, they may still be held accountable. And I think that this is a good thing.
