Another one is: Don't use GPS in your own city. Try to learn where you live. Read the map in advance if you are going somewhere new and memorise the turns.

A shocking number of my coworkers plot every single trip (even to work!) and claim this helps with traffic or undercover cameras or some other cope. But the traffic will be there regardless, and they shouldnt need Google Maps to remind them not to speed. They'd rather be glued to the screen than pay attention to their surroundings or learn any landmarks.
