On our last vacation we used Google Maps to get home. Except it messed up and added 9 hours to our drive time without us noticing.
It took me 26 hours to go from Colorado to Tennessee via gps the other day.

Oh no! Why do long? Did you walk?

No, Maps put me on a road that made me drive an old cattle line across Kansas without me knowing.

That stinks, but I am sure you got to see a lot of nice scenery. 
assistant
Flat and cows for all of creation.
