A GPS is like any other tool. You decide what the tool is going to do. Tools makes no decisions. A hammer is used for pounding and a saw is used for cutting. Likewise a GPS is used to calculate positions and the new ones calculate routes based on whatever bad data they have. We need to be able to tell when the recommendation is flawed.

Do not mindlessly follows GPS directions and you won't have to blame the GPS when you get stuck.
