LANSING — Cars that drive themselves may be safer, smarter and more efficient than those driven by people. But will they be better for the environment? It’s a question with no definitive answer, said John DeCicco, a research professor at the University of Michigan’s Energy Institute and a board member of the university’s MCity – an entire city for the testing of the vehicles, complete with cutouts of pedestrians and stoplights. Some aspects of the vehicles could greatly reduce energy use and emissions, while other aspects could increase emissions, said DeCicco. Driving efficiency improves greatly with an autonomous infrastructure.
