My first thought was it's the county's fault.
I am all for tech companies being held liable for what they market. Especially here, because at the end of the day, Google doesn't even care about providing you directions They just want your data that they can resell. But that's not how they market Google Maps.
I also think the county should be responsible, but that is in addition.
Most of the open source ecosystem would evaporate immediately if "SOFTWARE PROVIDED AS-IS" wasn't a legally-enforceable culpability abrogation.
If Google marketed Maps as "for information only", then that would be different.
I don't think we can call that "buried" unless we're operating under the legal theory that nobody is held accountable to terms and conditions at all anymore.
If I print a map and sell it showing a bridge. Then later the bridge washes out in a flood, how in any way would the map maker be responsible if you're aware enough not to drive off a cliff. This case has nothing to do with any technology involved.
Counties, in general under law, are excluded from most of these kinds of liabilities in most states. Probably why the family is going after Google, County is a dead end.
That is what the lawsuit is claiming. I still don't think Google is at any fault in this scenario, but it is a little surprising that the route still shows after several years of the bridge being out (and multiple reports to Google about it.)
In the case of Google Maps, the thing claims live data and gives you authoritative instructions like "turn left".
People have tendency to follow instructions and trust the computer, so if the computer says something people try their best to do it. Combine that with the illusion of live data, there you have a disaster waiting to happen. After all, the device that knows how much traffic is there at this very moment at particular location must also know if there's a bridge or not, right?
Google Maps is not a free product at all, it's a commercial product provided for free as part of an ad business. It's free as the free soda with the hamburger.
Is Google Maps responsible? I don't know but I can imagine someone claiming it due to the way information is displayed on the UI. Google maps always shows the information from position of authority, they are always very sure about the information they have and you don't have a clue about how certain they are bout what they tell you. I had multiple situations where Google Maps will direct me very confidently to roads that don't exist and once I had to stop and investigate if the road that Google Maps insist on is viable and the other time I had to turn back as the road conditions deteriorated from SUV-needed to T-80 tank needed. Negligent local authorities combined with authoritative assistant who is wrong and can't tell its wrong can be dangerous.
Maybe a UI with more clear communications is needed?
