Do you trust GPS directions?

If you have a driver’s license, chances are that you also have an amusing story about GPS directions.

Here’s mine: A few weeks ago, my family and I were driving from Cayucos, Calif., to Prescott, Ariz., when I noticed that the needle on the fuel gauge was pointing to “empty.” Not a problem, I thought. There must be plenty of service stations between here and Bakersfield.

We’d entrusted our route to the Google Maps app on my iPhone; it had never steered us wrong. The program assured me that yes, the winding road between Santa Maria and Interstate 5 was the fastest, most direct route to our destination. It even showed me the gas stations along the way: a Texaco, an Exxon and a Chevron.

Wrong on all counts.

Our “direct” route took us on a narrow two-lane road through Central California’s hill country, a sparsely populated part of the Golden State. By the time we reached the promised location of the first gas station, the “E” light was glaring at me from the dashboard and we were running on fumes. But the station was nowhere to be found. That was about when we noticed the refineries and realized that our helpful app couldn’t tell the difference between a gas station and a fuel processing plant.

Directions offered via smartphone through a mapping service such as Google Maps or Mapquest and aided by the Global Positioning System (GPS), the satellite-based navigation system that provides location information, have always been a little iffy. But recent advances hold the promise of change.

Google has unveiled what it’s calling a “next generation” update to its maps program that will allow it to map off-road locations; a spokesman told me that the company is also making all its directions “more accurate.” And Apple, maker of the uber-popular iPhone, has announced that it’s developing a new mapping application that will be available with its latest phone operating system. With two leading GPS apps in your smartphone, you’ll be able to plot a route with both to see whether they agree; if they don’t, you can consult a “real” map or just ask for directions.

It’s not yet clear whether the upgrades will arrive in time to benefit summer travelers. If they do, it won’t be a moment too soon.

Susan Miller, a communications consultant in South Florida, recently asked her Garmin GPS device to plot a course from Plantation, Fla., to SeaWorld in Orlando. Instead, the map led her to the SeaWorld gift shop at Orlando International Airport. (Fortunately, the theme park is only a few miles away.) “I thought we were headed in the wrong direction, but I kept doing what it told me to,” says Miller. “It was exasperating.”

An experience like that might be a one-time annoyance to some travelers, but it can be a big problem for travel-related businesses, such as Chehalem Ridge Bed & Breakfast in Oregon’s wine country. An error in Google Maps and other GPS-based mapping applications sends visitors on a two-mile detour down a gravel road, says innkeeper Kristin Fintel. “It’s frustrating for me, knowing that our guests were inconvenienced and that potential guests reading reviews might avoid us because it was a challenge to find,” she says.

Google says that it’s “aware” of the Chehalem mapping mistake and has made a partial fix.

Such problems aren’t new. Ever since GPS devices became available to a mass audience, complaints about circuitous directions have been a mainstay of the American road trip experience. Tales of nonexistent highways and bridges and harrowing turns down one-way streets make road-trippers chuckle and say, “Next time, bring a real map.”

And certainly, a paper map is a good idea if you’re visiting a place with poor cellphone reception or sparse power outlets. After all, when your phone or portable GPS unit runs out of juice, you’re as good as lost.

For some drivers, a better GPS experience is already in their grasp; it’s just a matter of paying attention. Rich Owings, an expert on GPS maps who publishes an online gear review site called GPS Tracklog, says that users often forget to update their software before they take a road trip, so their maps aren’t accurate. “When your settings aren’t right, that’s when people will end up routing over gravel roads,” he says.

And David Bakke, who edits the personal finance site Money Crashers, says that drivers often don’t bother to double-check their destination to make sure that the system didn’t identify the wrong place with a similar name. (Like, um, making sure that it’s a Texaco gas station instead of a refinery.)

Lynda Trujillo, a blogger who specializes in European travel and has had her share of misadventures with GPS directions, says immediate and constant user feedback to the app providers is the only way to keep the maps accurate. “They should set up a pop-up window that allows consumers to rate the route’s accuracy, or include a tab for easy reporting,” she says. “Something easy, like radio buttons you can click, with options to report a glitch.”

Maybe they will. If they’d offered that option when we were driving through the hills of California, I would gladly have given ’em a piece of my mind. We were within miles of running out of fuel, thanks in no small part to my all-knowing app. Just in time, we coasted down a gentle incline into the Central Valley off I-5, rolling to a stop at the first real service station since Santa Maria.

Some say that smartphones are getting smarter than humans, but after almost being stranded on a lonely mountain road, I know that isn’t true.

    Gotta use the GPS in conjunction with a paper map.  Wonderful advice about updating maps before a road trip.  I would have never thought about it, being a newbie GPS person. 

     And Chris … NEVER travel on less than half a tank of gas!  Just ain’t worth the stress.  Besides, it’s good to get everybody out running around the car for a few minutes.

    Just this weekend I was using a GPS/maps app on my smartphone to get walking directions to a place c. 1/4 mile away. The directions it showed looked odd and I realized the thing had located me in the center of a large multilane highway, a hundred yards from where I actually was. I could not get the thing to recalculate the route … it simply refused.

    The only thing I could do was close the app, reopen it in map-display mode (rather than navigation/directions mode), press the GPS locator button, and literally force the thing to get the highest-resolution reading. Only then could I put in my destination and get a reasonable route.
    It turns out the app bases its directions on a reading produced at the lowest level of GPS resolution, unless you have already forced it to a higher resolution.

    The glaring question is: “Why on earth was it designed this way!?” Why didn’t the app just immediately get its best-possible reading, right at the start? Why did I have to play with the app in order to improve its results?

    On top of that, the steps I needed to take in order to get the directions (i.e. the incorrect ones) in the first place, was ridiculous. I had to open the app, press a button in order to type in a destination, then press a button in the results map to get directions, then I had to press yet another “navigate” button in order to get it to actually show them to me. Huh? In what twisted universe does that make even the slightest sense?

    I agree that the quality of maps built into GPS devices/software is an issue, but beyond that, there are just way too many poor design decisions built into GPS software & devices, additionally. They also need to be cleaned up.

    I’ve been on the road twice now with two different people with two different GPS units and they screwed up royally both times. However, Maps on my iPad seriously rocks.

    I know that sometimes the best directions aren’t given.  I’ve tried it out in my own neighborhood, and the directions I get are contorted just to get to the freeway.  By now I know the best way to get to the main streets, but that little box always tells me to take a route that I know adds both time and distance.

    When I go to visit a friend in England, I love it when he uses his GPS because it says in British game show host voice ”This is NOT the winning way!”

    This past winter, a friend was driving at night in the middle of nowhere following the directions on her GPS.  Unfortunately she missed the sign that said road closed (and the GPS hadn’t been updated for the closure) due to the bridge being out over the river.  Thankfully she’s alive to tell the tale.

    At least yours didn’t insist you turn right – right into the lake!  HAHA

    That is TOO good, Raven!

    If the format of delivery has no bearing, why are we not reading story after story of people who were misled by following their paper maps? There is little doubt that paper maps in general are more accurate than computer generated instructions.

    one of my siblings used a GPS years ago to get to Disney World.  It brought her to the employee entrance parking/gate!

    I have to give a yes and no to this.

    I bought a Garmin with North American and European maps 3 years ago for our trip to Ireland. We spent 5 days driving around the country, (Dublin, Cork, Kilkenny) and it was perfect every time, never sending us the wrong way. I don’t know how many times we would have gotten lost without it.

    I update my North American maps quarterly. Last year we were in Galveston, TX when we had some car problems. According to the GPS, the auto chain we use had a location nearby so we drove to it.  When we got there, all we could find was an apartment complex. I spoke to a police  officer who was nearby, he told me the tire company had sold the property to the apartment developer more than six years ago, but the GPS apparently did not know that.

    We drove from Central Texas to the Texas Panhandle this weekend. GPS worked well on the way up there. On the way back however it kept trying to send me on the shortest route (through a lot of small towns) rather than the slightly longer route that put us on 300+ miles of interstates and only took a few moments longer. So, as we drove on, I got 2+ hours of instructions to go the other way, make a u-turn, get off the highway as soon as possible. Eventually it understood where I was going, routed me correctly, and took more than an hour off of our expected arrival time.

    So, I have had good and bad with GPS, I trust my Garmin more than my phone GPS, but feel that an understanding of the area I am driving in is crucial to getting to my location successfully.

    I personally love the Hertz Always Lost and it telling me to turn right now while on the middle of a bridge in Vancouver.

    Also, with living in Las Vegas, I used the GPS on my cell to find a place for an interview. I never left the 95 and it kept recalculating my route because it kept insisting I got off.

    The riskest part of directions is the sketchy neighborhoods they can send you through . . . when GPS was a red on grey screen with an arrow pointing the way-  my GPS sent me thru a pretty bad part of town – my new rental car had tomatoes thrown at it - 

    Even harder to the apps that do directions and to the self-contained GPS itself is do you keep people out of bad parts of town – and how do you tell the boundaries of those areas  . . .. the bad press and the implications of doing so – in the event nothing happens – and in the event does  - make programming routes an interesting business -

    Trust but verify.  And use some common sense, please.  I’m in the PNW, where we’ve had several tragedies attributable to GPS devices sending people on “shortcuts” over closed, unmaintained logging roads.  That’s all too often a fatal error– remember the Kim family.  If it doesn’t look like much of a road, assume it’s not much of a road and call for local directions.

    On our last trip it sent us over a very narrow bridge (very tight), down a dirt road only to stop in time before we could not get out pulling our Airstream. Luckily a  home owner came out, knowing we were in trouble, showed us a place we could circle around, so we backed up  quite a ways to it and he sent us to the right road.
