Sometimes it is good to remind ourselves that we need to temper our dependence on technology with good human judgment. A recent bug in the direction system in Google Maps sent drivers into a tail-spin and instructed them to make over 200 U-turns to get from Pennsylvania to their destination in New Jersey. Google has fixed the problem and the drivers are cured of "blind faith" in technology. (click map to see larger image)
GPS navigator systems are also becoming more popular in cars and in portable versions but they too don't always get you where you expect to go. Occassionally, they don't find the best route or have software that is not updated and may send you into a blind alley.
In both the real and online world, a reality check can be helpful.
