PROVIDENCE, R.I. – A self-driving shuttle got pulled over by police on its first day carrying passengers on a new Rhode Island route. Providence Police Chief Hugh Clements said an officer pulled over the odd-looking autonomous vehicle because he had never seen one before. "It looked like an oversize golf cart," Clements said. The vehicle, operated by Michigan-based May Mobility, was dropping off passengers Wednesday morning at Providence's Olneyville Square when a police cruiser arrived with blinking lights and a siren.
