      One evening in February 2007, a student named Paula Ceely brought her car to a stop on a remote

road in Wales.She got out to open a metal gate that blocked her path.That's when she heard the whistle

sounded by the driver of a train.Her Renault Clio was parked across a railway line.Seconds later, she

watched the train drag her car almost a kilometer down the railway tracks.

    Ceely's near_miss made the news because she blamed it on her GPS device(导航仪). She had never

driven the route before.It was dark and raining heavily.Ceely was relying on her GPS, but it made no

mention of the crossing."I put my complete trust in the device and it led me right into the path of a

speeding train," she told the BBC.

     Who is to blame here? Rick Stevenson, who tells Ceely's story in his book When Machines Fail Us,

points the finger at the limitations of technology.We put our faith in digital devices, he says, but our digital

helpers are too often not up to the job.They are filled with small problems.And it's not just GPS devices:

Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless

keyboards.

      The problem with his argument in the book is that it's not clear why he only focuses on digital

technology, while there may be a number of other possible causes.A mapmaker might have left the

crossing off a paper map.Maybe we should blame Ceely for not paying attention.Perhaps the railway

authorities are at fault for poor signalling system.Or maybe someone has studied the relative dangers and

worked out that there really is something specific  wrong with  the  GPS  equipment.But  Stevenson

doesn't say.

     It's a problem that runs through the book.In a section on cars, Stevenson gives an account of the

advanced techniques that criminals use to defeat computerbased locking systems for cars.He offers two

independent sets of figures on car theft; both show a small rise in some parts of the country.He says that

once again not all new locks have proved reliable.Perhaps, but maybe it's also due to the shortage of

policemen on the streets.Or changing social circumstances.Or some combination of these factors.

     The game between humans and their smart devices is amusing and complex.It is shaped by economics and psychology and the cultures we live in.Somewhere in the mix of those forces there may be a way for

a wiser use of technology.

       If there is such a way, it should involve more than just an awareness of the shortcomings of our

machines.After all, we have lived with them for thousands of years.They have probably been fooling us

for just as long.
