Amen!!! I agree completely that GPS gizmos in cars represent a step backwards! ABSOLUTELY!!!!
My wife had to run out yesterday and grab some additional parts for a job we were on. Our supplier is clear across town, and we were working in an area that she's completely unfamiliar with.
She used the GPS app in her phone to guide her to the job site, and wouldn't you know it - the darn thing tried to route her in the most circuitous path imaginable. Even being unfamiliar with the area we were in, she managed to bypass most of the crazy directions from her GPS, and found us.
