General Motors announced a 200,000-mile expansion of its Super Cruise HD map database network, over which the hands-free driving system will be able to run using its combination of LiDAR map data, computers, and radar. As opposed to Tesla’s Autopilot or its Full Self-Driving functions, Super Cruise was implemented with a very specific set of driving tasks in mind—interstate driving. Previously, the system focused on 200,000 miles of specifically divided highways that connected geographic regions, metropolitan areas, and the country as a whole. Now, with 400,000 miles of mapped and tested roads available, Super Cruise users can drive hands-free on certain undivided state highways and additional divided federal routes.

Of course, GM can’t be the only manufacturer from the Big Three to implement semi-autonomous technology. Ford’s BlueCruise system is a direct competitor to GM’s Super Cruise, though the systems use slightly different technology. Notably, there is a lack of LiDAR on the Ford models. Specific differences aside, just a month after Super Cruise updated its system, Ford followed with an updated BlueCruise 1.2 system last week. While no additional roads were added to the BlueCruise maps, it did add a host of new driving safety technologies including in-lane repositioning and predicative speed assist.
The main functions of Super Cruise and BlueCruise are autonomous acceleration or braking in order to maintain a selected following gap from a vehicle ahead. The systems can also maintain lane position and can perform both driver and system-initiated lane changes to pass slower traffic and to move from a lane that may be ending. It does all this while monitoring the driver’s head position and/or eyes in relation to the road to help ensure driver attention. Both systems are considered Level 2 of autonomy by the SAE autonomy scale.
Specifically, GM announced historically significant roadways like Route 66 and enthusiast havens like the Pacific Coast Highway and US Route 1 are now available. Canadian customers will be excited to hear that the Trans-Canada Highway is now an available route. However, these roads aren’t the only exciting additions to the Super Cruise technology.
