I saw this amazing video of a runaway John Deere tractor destroying the parking lot of a Walmart outside of Toronto. I would love to see how the liability issues emerge on this one. Product liability may be one given the ability of the tractor to run amok without a driver.
For many years, one of my sisters, Jennifer, and I had an annual competition of finding the worst movies ever. One year I won with Killdozer, a 1974 film of a bulldozer that becomes possessed by a strange glowing power from a meteorite. The bulldozer proceeds to chase six construction workers around an island off the coast of Africa. Cinema genius. (My other winner was Nazi zombie film, Shock Wave, where Nazi zombies inexplicably come to life on an island wearing swimming goggles and chase a ship wrecked group around the grounds of a mad Nazi scientist).
This video clearly shows the need for a sequel to Killdozer. Indeed, lawyers for Deere should look into any sightings of mereorites in the area.
