Autonomous shuttle startup May Mobility expands to a third U.S. city

May Mobility launched its first low-speed autonomous shuttle service in Detroit this summer. By March, the Ann Arbor, Michigan-based company will be operating in at least three U.S. cities. The company, which just announced plans to expand to Columbus, Ohio, is planning to add another route in Grand Rapids, Michigan. It's a rapid acceleration for a company that was founded less than two years ago. May Mobility is different from other companies racing to deploy autonomous vehicles at a commercial scale.
