Self-driving cars parked

NuTonomy and Optimus Ride have agreed to suspend their self-driving car tests in Boston in the wake of Sunday's tragedy in Arizona, where an autonomous Uber vehicle killed a pedestrian. "We are working with City of Boston officials to ensure that our automated vehicle pilots continue to adhere to high standards of safety," a nuTonomy spokeswoman said in a statement. "We have complied with the City of Boston's request to temporarily halt autonomous vehicle testing on public roads." Karl Iagnemma, chief executive of nuTonomy, said the response to the crash will be vital for the future of driverless cars and whether passengers are willing to ride in them. "The reality is we may work very hard as technology developers and end up with a technology that members of the public are uncomfortable with," Iagnemma said, speaking at an event in Cambridge last night.
