WASHINGTON, May 16 (Reuters) - The U.S. Justice Department said on Tuesday that it had charged a former Apple Inc (AAPL.O) engineer with attempting to steal the firm's technology related to autonomous systems, including self-driving cars. The engineer, whom Justice Department officials named as Weibao Wang, 35, in 2017 accepted a U.S.-based job with a Chinese company working to develop self-driving cars before resigning from Apple.
