WASHINGTON, Jumada II 06, 1437, March 15, 2016, SPA -- A U.S. robotics expert is warning against a rush toward widespread deployment of self-driving cars, saying they are "absolutely not" ready, according to AP. The director of Duke University's robotics program, Missy Cummings, told the Senate's commerce committee the cars aren't yet able to handle driving in bad weather, including standing water, drizzling rain, sudden downpours and snow. She says they certainly aren't equipped to follow a policeman's directions. She also says it's relatively easy for hackers to take control of the GPS navigation systems of self-driving cars. Privacy of personal data is another concern. General Motors and Google officials say they're concerned that a patchwork of state and local laws regarding self-driving cars will hinder deployment. They want federal regulators to speed up rules to help get the vehicles on the road. --SPA 23:31 LOCAL TIME 20:31 GMT www.spa.gov.sa/w
