U.S. Plans to Update Self-Driving Guidelines in Coming Months

"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.

"We don't want rules that impede future technological advances," Chao said.

Chao was not specific about what her department's proposals would include, or how they would differ from policy guidance proposed by the Obama administration.
