The Mobility Transformation Facility will open this fall in Southeast Michigan, right in the heart of the auto industry. It’ll simulate both a four-lane highway and a city intersection—two very different environments with very different dangers. Just recently, Google announced that after driving its autonomous cars for thousands of miles through suburban Mountain View, it’s shifted to focus on teaching its autonomous car to drive in cities.
With a university behind it, I’m guessing this one will get built, unlike another proposed fake city that was also intended as a testbed for new technologies.
