Ghost town tests self-driving cars of tomorrow

Tucked away on a tree-lined US college campus, a sprawling ghost town has been built to test the self-driving cars of the future.

MCity, which sprung up in an empty field a year ago like a Hollywood set, is where new technologies which are already radically reshaping the automotive industry must prove themselves before they make it to regular roads.

The 13-hectare site offers all the trappings of urban life, designed to reproduce the kinds of situations a self-driving car would encounter, like a child dashing into the street after a ball.
