Self-driving shuttles arrive in Columbus this week

In the crowded streets of San Francisco, companies such as Uber and Cruise Automation have been testing self-driving vehicles for years now. In suburban Phoenix, hundreds of autonomous Waymo vehicles are driving as many as 25,000 miles per day. There are, in fact, dozens of cities around the world hosting pilot programs for self-driving vehicles. The latest addition to that list is Columbus, Ohio, where a series of self-driving shuttles are being deployed on city streets this week. The electric, low-speed vehicles -- operated by the Michigan-based start-up May Mobility -- will begin testing and mapping local streets before accepting passengers in December, the company said. Eventually, there could be as many as 10 shuttles operating in downtown Columbus.
