Pontiac's famous tagline is "We build excitement". What does it say about the new Pontiac G8 that yesterday morning an Australian engineer driving a test car fell asleep at the wheel and piloted it down a 100-foot embankment, striking a boulder and flipping the car end over end? Well, the Pontiac G8 will surely be one of the more exciting vehicles from the brand in recent memory when it goes on sale early next year, but apparently for the engineer, 41-year-old Rolf Glenk, it wasn't exciting enough to keep him awake. Glenk was the last in a convoy of G8s that were traveling on Highway 82 in Colorado yesterday morning when the accident happened. Being last in line, it was only after another engineer noticed their group was one short that Glenk and the totaled G8 were found flipped upside down at the bottom of an embankment. Glenk was taken to Aspen Valley Hospital and treated for minor injuries, while the G8 didn't so fare nearly as well. Glenk was also given a citation for careless driving.
