Spanish artist Maider Lopez stranded 160 vehicles on a typically empty, verdant road to display the impact of cars on the environment. It's fairly clever — unless you didn't intend to be part of an art installation.

The event took place in 2005 and clogged up roads for more than five hours. Photos of the event are now on display as part of an exhibit entitled "Auto. Dream And Material" on display at the Laboral Centro de Arte y Creacion Industrial in Gijon, Spain. [Laboral Centro De Arte via Inhabitat]
