Apple Self-Driving Car Rear Ended During Road Testing

The safety of self-driving cars has become a source of concern for U.S. transportation regulators this year after one of Uber Technologies Inc's [UBER.UL] vehicles struck and killed a woman in March in Arizona, prompting the company to shut down its testing efforts for a time. Uber has said it plans to have self-driving cars back on the road by the end of the year.
