This reminds me of that guy who posted here awhile back complaining about his gps directing him down an unpaved road...

BERLIN (Reuters) - An 80-year-old German motorist obediently following his navigation system ignored a motorway "closed for construction" sign and crashed his Mercedes into a pile of sand further down the road, police said Monday.

"The driver was following the orders from his navigation system and even though there was a sufficient number of warnings and barricades, he continued his journey into the construction site," a police spokeswoman told Reuters.

"His trip finally ended when he wound up crashing into a pile of sand," she added.

The driver and his wife escaped uninjured from the collision, which occurred on a motorway near Hamburg.
