I would usually agree but there was no barriers I am not sure about signage. While I think the driver should always be aware of where they are driving they honestly set him up for failure. On top of that Google had a decade to fix the route and didn't.

If there was signage, that at a minimum would make it his fault.

Because they’re not blindly trusting Google maps, which is why Google is only one of those in the lawsuit and not the most culpable.
