“Google Maps sends 18 wheeler trucks , Greyhound buses, and .. up jeep roads..”
Some years ago when Google maps and in car GPS were somewhat new (at least to me), I was in very rural East Texas trying to get to a place that had a truck tailgate I needed. Google maps did send us to the right location via the shortest route. BUT a good part of the trip was on a muddy one lane dirt road, ditches were full of water, no place to turn around. I was in a two wheel drive 3/4 ton pickup with highway tires. I kept praying that we meet didn’t another oncoming vehicle. We didn’t but I am now very careful with that tech.
There are a lot of Class VI roads in my town.
Visitors came from Ireland, rented a car in Boston, and called us tilted 45 degrees stuck on a boulder on the back side of a “mountain” (big hill).
They DID follow the shortest route.
