Oh yes, I agree with that completely. Shared liability for sure, but Google deserves liability for not making changes for a decade that they were notified to make. Surviving family should definitely sue both, but neither should be let off the hook for sure.

If this were one-off, maybe. But it's not the first time navigation has sent people off dead end roads.

In low visibility, we are trained to rely on our navigation so while there is also some personal responsibility, you may also not see it until it's too late. Nothing negates the responsibility of everything else involved.
