My mum told me I was giving her directions from my car seat...so I have always had a natural sense of direction and spatial awareness. If I have been to a place at least one time, I should be able to find my way there again. If I'm going someplace new, GPS sure beats printing out like 5 pages of instructions.
Strongly disagree with the OP's implication that GPS makes drivers worse. Telling you the name of your exit which you prob don't know the exact name of, the lane you need to be in, traffic patterns, and alternate routes you never considered, and more are huge helps to your driving ability.
This is a gaming site, let's make it simple...GPS is pretty much a mini map for IRL
