GM testing autonomous Bolts on Michigan's public roads

DETROIT – General Motors has started testing fully autonomous vehicles on public roads around its technical center in suburban Detroit. The announcement comes just one week after Gov. Rick Snyder signed legislation that allows the cars to be tested on public roads without a driver or a steering wheel. But the automaker says that for now, it will have human backup drivers for its fleet of autonomous Chevrolet Bolt electric cars. Testing started Thursday on roads near the tech center in Warren, Michigan. The Bolts will soon move to the entire Detroit metro area, which will serve as the company's main testing center for snowy and cold weather.
