GM’s Super Cruise will cover 400,000 miles of North American roadways, more than doubling coverage

However, there are many driving responsibilities that Super Cruise will be unable to execute. The technology does not communicate with the vehicle’s navigation system in such a manner that drivers may enter a location and let the car handle all required turns and lane changes.

Furthermore, Super Cruise cannot manage traffic signals or stop signs, thus the system will alert the driver when a junction is 350 meters away (or 500 meters for non-VIP cars) so that they may take control of the vehicle. On two-lane highways, Super Cruise will not enable automated lane changes. In other words, it will not cross broken or solid yellow lane markers.

What it will be capable of is managing driving on a more diverse range of road types. Some stretches of the Pacific Coast Highway, for example, are exceedingly sinuous, with barely the smallest amount of room between opposing lines of traffic. According to GM, the system’s usage of high-definition maps of those routes will allow it to safely and confidently cope with every twist and bend.
