GM Super Cruise self-driving car tech gets virtual playpen

GM is ramping up its self-driving car tests, using a new high-speed 360-degree simulator to test its upcoming Cadillac Super Cruise tech without having to fully build the vehicles first. Cadillac expects the first Super Cruise equipped models – which will take on some of the responsibility when on highways and in traffic – to appear in showrooms within the next 5-6 years, and has in fact already begun real-road testing of some prototypes.
