Perhaps a bit of “blind faith” on both the driver and GPS systems part.

“In computer programming blind faith (also known as blind programming or blind coding) is a situation whereby a programmer develops a solution or fixes a computer bug and deploys it without ever testing his creation. The programmer in this situation has blind faith in his own abilities, but this often results in catastrophic failure.” http://en.wikipedia.org/wiki/Blind_faith_%28computer_science%29

In the end the driver is responsible. Even airplane pilots, who must learn to trust their instruments, do not discount visual cues to operation (most of the time).

I’m enjoying your book, thanks Tom.

Last night, my partner and I were driving from Denmark on our way to Calais and while we passed Eindhoven we passed some roadworks on the motorway, trusted the GPS while ignoring the signs and drove left where we should have gone right. As the roadworks had removed some junctions we had to drive several miles more than the GPS suggested in order to turn around, only to find that we did not end up on the right motorway and now had no clue as to where we were or how to get to Calais.

During our roundtrip on the junctions and motorways, I noticed that a lorry was following us and most likely also lost.

In the end, we asked a local man that could guide us back to the motorway so we could proceed to Calais.

I just learned something new. Thank you. I always had my doubts about GPS devices and it’s interesting to see it proven that they can lead to a lack of situation-awareness.

As if you weren’t blind enough using a GPS, how about a new app for your iphone that makes it “easier” for you to walk (or drive) and text at the same time. I came an app for iphones called Type n Walk, by CGactive, LLC. The app uses the camera to give you a picture on your screen of what is ahead of you while you text. So, you have the illusion of knowing being safer as you walk, into traffic, not seeing the car to your right. Or better yet, it give you the illusion that you might be able to text and drive, all warnings aside of course. The Apple App’s store has an option to protest, ie is this offensive. I said YES and I encourage others to object as well.

Nick, I have a similar experience with Tele Atlas.
I reported a “missing link” months ago, but their maps still seem pretty sure that I have to walk or bike a couple of hundred extra yards to get into my village…

I own a farm in a semi-rural area, and a couple of years ago Tele-Atlas, the company that supplies the mapping information for many GPS devices and to Google Maps, incorrectly started showing that my driveway was a road that connected to the next town over. Since then, every summer I get a stream of drivers who come down my driveway, drive around for a while, and leave. If I’m there when someone pulls in I’ll try to politely but firmly tell them that a) they’re not going where they think they’re going and b) it’s not a road, it’s my driveway. Most people will argue with me! Some get quite belligerent.

For a while I tried gating the driveway but my gate got driven through. Twice.

I’ve reported the problem to Tele Atlas but they have been no help.

Many of the newer city buses I ride to work are equipped with GPS systems that are set to announce the upcoming stop so the driver doesn’t have to. They work fine until we get downtown and into the thick of the 30+ story buildings, whereupon the system gets confused as to it’s location and starts announcing stops too early. (So when we’re approaching the 4th street stop, the voice is saying that we’re coming up to the 5th street stop.)

I can’t help but think that a car GPS would be similarly confused under the same conditions, and considering that our downtown has alternating one-way streets, one block off can mean turning directly into oncoming traffic.

I think I’ll continue to look at a map before setting out, and then rely on my MK 1 eyeballs to find my destination.

NY is having a lot of problems with GPS systems leading Commercial drivers onto parkways. As I’m sure you are aware, the parkways in NY have low bridges and trucks are not permitted. There was an article on RyePatch:
http://rye.patch.com/articles/fixing-truck-strikes-may-cost-big-bucks

about the Hutchinson River Parkway’s King Street Bridge in Rye Brook, NY on the NY-CT border.

“The King Street Bridge in Rye Brook, for instance, which is under the jurisdiction of the county, is actually the most struck of any bridge in the state. It has already had three bridge strikes in 2010 and had nine strikes in 2009.

In 2009, the county police – who patrol the Hutchinson River Parkway, Bronx River Parkway, Saw Mill River Parkway and the Cross County Parkway – dealt with 54 bridge strikes, in 2008 they dealt with 46, nearly one bridge strike a week.”

Pretty good article.

On another note, Tom, I really enjoyed Traffic…in fact, I read it twice. I am a college student in upstate NY and I am an Environmental Science and Policy major. In a few years, I plan on going to grad school and hope to work in urban planning or something in transportation. If you have any advice or guidance, let me know! I would love to maybe have you talk at my college or just talk one-on-one.

Just last night, my GPS wanted me to turn left at an intersection that was clearly marked as “no turning”. My wife was watching the GPS and urged me to turn, not realizing that it was illegal.

In fact, I was at the scene of the fatal crash mentioned above, several months ago, and my GPS showed me driving through a field.

A GPS is great but no substitute for looking out the windows.
