A paper map would have worked no better as this was a road change.
I always check the path the GPS recommends before I take it. Back in the early days, I would ignore the GPS if I identified a better route on the paper map but I eventually found out that 95% of the time, the route recommended was faster that the route I picked on a map. I still double check because of the remaining 5%.
Despite the occasional error, I would not give up the GPS, It knows traffic conditions and road changes my now several year old map does not.
I don’t know what the solution would be in this case, I would hope that there was signage indicating the road change and the lost drivers just ignored or missed it.
What, people forgot how to read road signs?
GPS navigation is a useful assistive technology if you realize it’s usually gonna be wrong at least once from any given point A to point B.
They’re also nearly 100% wrong for choosing optimal routes when one has a good knowledge of local driving conditions.
I study and print out backup paper maps when I aim for unknown destinations, and between the GPS and the backup maps I usually do pretty well.
Just wait until they start renaming streets like the left wants. Confusion galore.
