Who cares? Do that many of you actually use GPS on a day-to-day basis? Learn how to read a map and how to use a compass! It's not that hard. Hell, if you're having that much trouble navigating, maybe you shouldn't be driving (or hiking, or camping) in the first place.
This is mostly going to affect air traffic, who rely pretty heavily on GPS systems.
No joke. If you can't get anywhere in your car without a GPS, you're in trouble anyway.
If you're out in the woods so far that you NEED a GPS to get back out, you're an idiot if that's the only thing you're depending on. You better understand basic land navigation and have a good compass and topo maps with you. A GPS is like anything electronic. It can fail at any time. You can lose reception. You're batteries can go dead. None of those are likely, granted, but if they do, you're screwed.
Even air traffic shouldn't depend solely on GPS. Nobody who doesn't understand how to navigate without a GPS should be navigating for an Airplane. It's a disaster waiting to happen.
GPS systems are great, but they don't completely eliminate the need for basic navigational knowledge.
