I love GPS – I have almost no sense of direction, and even when given clear directions, frequently follow them incorrectly.

However, I was reading this article in the Washington Post and it got me to thinking about the dark side of GPS.  Namely, that we assume the GPS device is smarter than we are and we throw common sense aside and blindly follow the route calculating algorithms built into our phones of PNDs.

When I’m driving in towns I’m familiar with, I frequently power up my GPS because I like to know how far I am from destination and the ETA seems pretty accurate when in town (when on the Interstate, it’s crap, but that’s another story).  However, I almost never follow the directions to the letter.

Heck, just last week I was driving up to Omaha for a concert just to get the exit number I needed.  It wanted me to take the wrong one.  Then when we took the correct exit, it wanted us to take the longer way.  All in all I turned the GPS on because I needed three turns, all three were wrong.  Had we blindly followed the GPS, out trip would have certainly taken longer.

When using GPS, the best tool in your arsenal is common sense.   If it seems wrong, don’t do it.  Of course, it’s easy to override the GPS when you’re in an area you know.  However, when you’re traveling I recommend having paper maps handy just in case or that you use a service like Mapquest to map out your planned route ahead of time just so you can see if something is really wrong ahead of time.  Mapquest certainly isn’t infallible either, but it tends to give pretty good directions, in my opinion.

Bad Directions

When following a GPS, it’s critical to make sure you pay attention to street signs… especially one way streets.  Most GPS devices know which streets are one ways, but they’re not 100% accurate so you always need to make sure that street signs match up with directions.

Keep in mind that there can be errors on maps as well.  I remember my first GPS was a TomTom and it had an error on Interstate 76 when heading to Denver.  It always wanted me to get off the interstate and take a couple highways to go around.  I never followed those directions because I knew it was wrong.  I finally figured out that the map in the system didn’t have Interstate 76 going straight through so it always wanted me to go around.

Of course, the experience I had that really takes the cake and constantly reminds me that I can’t be 100% dependent on GPS is an experience I had in Northern Colorado when driving to Steamboat Springs to go snowboarding.  It was my first time taking the trip my GPS was a shiny new toy to me at the time so I didn’t bother to grab my maps before I left.  I figured the GPS was smart enough to get me where I was going and since the route was pretty straightforward.

All went well through Nebraska and Wyoming until I about 30 miles from my destination.  For some reason, the GPS thought that a snowmobile trail was a road and it took me down a gravel road that then turned into a dirt road that then turned into a mud pit.  I nearly got myself stuck 15 miles from the closest town in winter in an area with no cell phone service.  Fortunately, I got out of the mud, backtracked to the previous town and got directions from a real human being.   While a major incident was avoided, I’ve always tried to be cautious with my GPS even though I love it so.
