I have been directed by google down roads that weren't actually roads.
When I was in Arches National Park, I noticed google trying to direct me to take an actual jeep trail instead of a paved road. Like, big sign at the turn out that said "high clearance, 4wd required. Do not attempt when wet" (the jeep trail actually crossed a river, which at that time was about 3 feet deep). And when i deliberately modified my path on my phone to not go down the jeep trail, within 2 miles of driving, google maps helpfully interrupted its own directions to say "we've found a route that will save you 30 minutes. If you don't want to take the new route, press ignore", which directed me back to the fucking jeep trail.
I feel like Google does have some culpability here, since they make it so hard to actually avoid hazards while still using their tool. Like, how is there not an option to just avoid dirt roads the way I can avoid toll roads? I don't dispute that it is ultimately the driver's responsibility to validate the program's outputs. But if the only way to use the app at all is to not validate the outputs, then I don't think a single line clause in the EULA is sufficient to shield google from liability.
