Sigh...
The problem is more with people not using their brains and just delegating all the decision to a fallible machine.
I remember when I got my first Garmin car GPS. For kicks I had it programed to take me from home to the Yosemite Lodge (which I already knew how to get there), Besides wanting me to go from Hwy 120 to Hwy 99 to Hwy 140 instead of sticking to Hwy 120 all the way to Yosemite, its biggest gaffe happened when I was already in Yosemite Valley on Southside Drive. Instead of instructing me to make a left over Sentinel Bridge to head over to the Yosemite Lodge, it instructed me to make a left and take Swinging Bridge over the Merced and then the bike path to Yosemite Lodge!
If that women in the story above was driving my car, I think she probably would have!
For goodness sakes, didn't this women realize that something was seriously wrong when the GPS instructed her to go off road? Geesh... Some people truly are just lemmings.
