In how many ways can your GPS go wrong?

An interesting and very educational article in Scientific American on this subject written by an acquaintance of mine....

Enjoy, and then treat your GPS position with an appropriate amount of skepticism.

I had my GPS showing the train was moving at 400+ MPH SW from WAS. I knew it was wrong for three reasons:

1) Amtrak (even on a good day) doesn't go 400+ mph!

2) There are no Amtrak tracks SW of DC, and

3) The train was sitting on the platform at WAS not moving!
