Google Maps provides pathways between start and destination, and attempts to optimize said pathways to reduce travel time or gas or whichever options you select. Google Maps does NOT provide any warranty or guarantee that the pathway provide is free of obstacles or hazards.
Put it this way: if that bridge were okay but there were a child standing on it and this driver hit the child, who it at fault? Google Maps for telling the driver "here is a pathway to reach your destination"? Or the driver for failing to observe a driving hazard in the roadway? How about if Google had reports there was a child in the roadway? Would the driver have any fault for hitting the child then?
Google provides a feasible route. The driver is - and always has been - responsible for ensuring that their vehicle is operated in a safe manner, which includes watching for and appropriately reacting to hazards. If the bridge had washed out an hour ago, everyone would agree it was the driver's fault for failing to watch for a road hazard. If it had washed out a week ago, everyone would agree the driver should have been watching the road and taking appropriate action to avoid hazards. But a little more time passes and suddenly the driver is absolved of their responsibility and we find someone else (conveniently someone with deep pockets!) to blame?
Absurd bullshit. Mostly performance outrage by people who just hate Google. Love Google or hate Google; map providers do not take on any responsibility for the safe operation of motor vehicles.
