GM begins testing autonomous cars on Michigan public roads

CEO Mary Barra also announced Thursday that GM will build an unspecified number of fully autonomous Bolts on the assembly line where regular Bolts are made, in order to gain expertise in building autonomous vehicles. The Bolt, which went on sale in California and Oregon this week, can go 238 miles on a single charge and costs about $30,000 when a $7,500 federal tax credit is factored in. Autonomous Bolts, which have distinctive spinning laser towers on their roofs, will come off the assembly line in Orion Township north of Detroit starting next year.
