A bug in Google Maps directed a driver to make more than 200 U-turns in order to get from Pennsylvania to New Jersey (click the image on the right). Google quickly fixed the error and now the same search points to the correct driving directions.
200 U-turns?! That driver's head is still spinning...
In both real and online world, a reality check is always a good idea.
