Future Uncertain For Autonomous Vehicles After Pedestrian Killed By Self-Driving Uber

After the collision, Boston's transportation department has asked Optimus Ride and nuTonomy, two self-driving car companies testing in the Seaport, to temporarily hold off until the department can review its safety procedures.
