Has anyone else noticed a sudden surge in the use of auto GPS receivers? It seems as if 1 out of every 10 cars I pass on the highway has a GPS receiver! They are easy to spot, especially at night when they look like a big glowing boxes mounted on the dashboard.
I don't like the idea of using GPS receivers to find my way around well defined routes. I think GPS receivers are more of a crutch than a useful tool for the average person. If you know how to read a map and follow signs, you shouldn't need a GPS receiver. For delivery drivers and anyone else who frequently travels to new places, I can understand the time saving ability of a GPS receiver, but for all you other drivers, learn to read a map!
If you're hiking a mountain or camping in unfamiliar or unmarked wilderness, I can see how having a GPS receiver could save your life. But trekking into such a situation without also knowing how to use a compass to find your way around is even more stupid than going unprepared all together.
Don't rely on electronics to do something you're capable of learning how to do. There is no electronic fix for human stupidity.
