Two driverless cars traveled some 300 miles today, crossing from Detroit over to Windsor, before making their way back into Michigan and up to Traverse City.
The road trip was part experiment, part advertisement: there's a big auto industry shindig happening in Traverse City right now and Michigan is really trying to cement itself as "the place" to build driverless cars.
So to show off, state and Canadian officials got two auto supply companies to do this test drive.
Both cars were in driverless mode on all the highways, and even underwater in the Detroit Windsor tunnel, says Kirk Steudle, Director of Michigan’s Department of Transportation. Although he says the cars got tripped up a couple of times, like right after the toll booths.
