This is the paradox. The computer knows the best route, better than you do, most of the time. But, you are not in control anymore. You are not the one making the decisions, figuring out where the turn is, and whether you want to turn there or at the next intersection. All I can say is, try leaving your phone at home for a day and get where you're going without it. You'll probably get there a few minutes later, but it will feel completely different.
I wish GPS systems had a “shut up until I get to the highway” mode and a “I've entered my neighborhood” button—the former is more important, as the later can be solved with “end route”. I do not need their (inaccurate) instructions on how to get in and out of my house.
