My analogy is more akin to using Google Maps (or any other navigation tool).

Prior to GPS and a navigation device, you would either print out the route ahead of time, and even then, you would stop at places and ask people about directions.

Post Google Maps, you follow it, and then if you know there's a better route, you choose to take a different path and Google Maps will adjust the route accordingly.

Google Maps is still insanely bad for hiking and cycling, so I combine the old-fashioned map method with an outdoor GPS onto which I load a precomputed GPX track for the route that I want to take.
