Which company is leading the way in testing of driverless cars?

The opening stretch belonged to others: Hyundai Kia Automotive Group led first, General Motors followed, and BMW moved into first by day 8. BMW then controlled the long remainder, finishing with 27.6%—just 2.6 points ahead of Audi.

That was enough to win an eight-option field, but not to command it: General Motors took 13.8%, Google 10.9%, and five others shared the rest.
