Uber tries to have it both ways with self-driving cars

Uber has ended its brief driverless car experiment in San Francisco -- though not before trying to pull off a bit of corporate gymnastics. Earlier this month, Uber announced it had brought "self-driving" cars to its hometown, with much fanfare. Two days later, however, Uber was clarifying that the vehicles aren't really as "self-driving" as the name suggested. In fact, they require a human operator. The clarification came after Uber refused to comply with California state regulations that require a special permit for companies testing self-driving technology.
