For users, there is an understanding that Maps is fulfilling a critical information role in our society and there is the underlying assumption of accuracy.
The interests of the user, the business and Google soon diverge quickly when innaccuracies show up in the system. It doesn’t matter whether the problem is caused by Google (think mergings) or by a third party (think hijacking), Google is going to see it as a statistical problem with a certain priority while the patient that went to the wrong emergency room or the business loosing income will view it as problem worthy of specific oversight and intervention.
Here was a post today in the Forums that is suggesting that Google should publicly and obviously recognize this difference with a Warning Label:
Google does place a warning on their driving directions:
These directions are for planning purposes only. You may find that construction projects, traffic, weather, or other events may cause conditions to differ from the map results, and you should plan your route accordingly. You must obey all signs or notices regarding your route.
