ANN ARBOR, Michigan — The University of Michigan's $ 10 million, 32 - acre «outdoor lab,» Mcity, is designed as a place where automakers and suppliers test semi-automated, autonomous, and connected - car systems, with
railroad crossings, roundabouts,
paved and unpaved roads, potentially potholes, snow and ice in the winter and, presumably, no distracted drivers to rear - end the autonomous cars.
