To the list of places testing driverless cars, add Las Vegas

Motional did not say how many cars had participated in the Las Vegas tests, but said in its statement that "multiple" autonomous vehicles had been used on routes that included public roads and closed courses. During the tests, the vehicles sensed and responded to human-driven vehicles, cyclists and pedestrians, the company said. Some tests were completed with a safety operator in the car; others were completed without one.
