Soon your Cadillac will change lanes hands-free with upgraded Super Cruise system

General Motors is inching closer to self-driving vehicles with the introduction of a new feature that will enable some Cadillacs to change lanes on their own. GM announced Tuesday it's upgrading its Super Cruise system to enable automated lane changing. The technology will safely change lanes when drivers signal they'd like to do so. Super Cruise already enables hands-free driving on fully mapped highways. It keeps the car centered in its lane, brakes, accelerates and notifies drivers when they must take over the controls.
