Trump to update self-driving guidelines

President Donald Trump's administration will unveil revised self-driving guidelines within the next few months, the head of the U.S. Transportation Department said on Monday, responding to automakers' calls for regulations that will eliminate barriers and allow autonomous vehicles on the road. 'The pressure is mounting for the federal government to do something' about autonomous vehicles, U.S. Transportation Secretary Elaine Chao said on Monday in Detroit. However, Chao told reporters the federal government should be careful before setting binding rules to govern autonomous vehicles. Companies including Alphabet Inc's self-driving car Waymo unit, General Motors Co, Ford Motor Co, Uber Technologies Inc, Tesla Inc and other are aggressively pursuing automated vehicle technologies. 'We don't want rules that impede future technological advances,' Chao said.
