Probably be an urban legend, but several years ago I heard a story about a guy who rolled his car, then sued the manufacturer because there was no warning in the owner's manual about the hazards associated with cornering at high speeds.
Or the allegedly factual lawsuit about the character who bought a new Winnebago-type "motor home" -- you know, one of those 30-foot monsters. This guy supposedly got onto the freeway, set his cruise control, and got out of the driver's seat and went in the back to make a pot of coffee!! Of course, the motor home left the freeway at tne next curve and rolled over...and he sued the manufacturor for not making clear warnings not to leave the driver's seat while the vehicle was in motion!!
The cute part was that he won the lawsuit.
I read this on one of those "craziest lawsuit" (the Rachel prize, or something like that) threads.
