Like ONSTAR was in my Camaro, just verbal directions and arrows. I never used that once. I did have a tablet that I could mount to my dash so that it could display Navigation with a MAP so I could use my common sense to double check, in the off chance that the computer had picked an invalid route (or one through a bad neighborhood). Waze in particular saved me from a few hours-long traffic snarls that without its input I could not have gotten around, due to complete unfamiliarity with side streets in that area. Having a MAP along with advise that I could follow or ignore, along with software that was capable of working to continue to guide me despite me making a different choice, was invaluable.
There is NO WAY I would attempt to navigate in a new city or country without at least SOME positional information to go with a map. The technology is useful. I see no need to behave like a luddite simply because "machines"
The people that stubbornly obey directions without reference to even a map are at fault, not the software.
I also blame "safety experts" who think that having in-car GPS display a map in transit is "distracting and unsafe" and insist on "no screen, directions only" GPS. Useless.
