They’ve been used in California, Las Vegas and at research universities across the country such as the University of Michigan. Now, a self-driving shuttle will begin a test program in downtown Detroit, marking the first test of autonomous commercial vehicles in the Motor City.

May Mobility, a startup based in nearby Ann Arbor, says it plans a five-day test program using two of its shuttles in downtown Detroit beginning Oct. 9. The shuttles, which can carry six passengers each, will be offered for use by employees of Quicken Loans and Rock Ventures, part of the business empire of Cleveland Cavaliers owner Dan Gilbert.
