Cadillac to add 70,000 miles to Super Cruise compatible highway network; hands-free driving by Q4 2019
Cadillac is expanding the availability of Super Cruise to an additional 70,000 miles of compatible, divided highways in the United States and Canada. This expansion will make the true hands-free driver assistance feature available on more than 200,000 total miles of compatible highways by the fourth quarter of 2019.
To date, Super Cruise has been available on more than 130,000 miles of limited-access freeways. The expansion builds on Super Cruise’s combination of precision lidar map data, high-precision GPS, a state-of-the-art Driver Attention System and a network of camera and radar sensors.
Some of the divided highways added will include limited intersections and traffic control devices. In the cases of railroad crossings, pedestrian crossings, stoplights or stop signs, Super Cruise will alert drivers to take back control of the vehicle. As always, it remains important for drivers to stay engaged and vigilant at all times while Super Cruise is engaged.
To enable the expanded functionality, an enhancement to the Super Cruise system will be available to 2018 and 2019 model year Cadillac CT6 owners through their Cadillac dealer. Following the completion of the system enhancement, the new, additional map miles will be sent to customer vehicles over the air throughout the summer and fall.
In addition to the mileage expansion, the software update will also include performance improvements, enhancements to increase Super Cruise availability and enhancements to the Driver Attention System. . . .
Customers have traveled 2.5 million miles using Super Cruise since its launch. Super Cruise is currently available on the 2018 and 2019 model year Cadillac CT6 and will be available on the 2020 model year CT6 later this year. Super Cruise will be available on Cadillac’s all-new CT5 sedan next year.
There's a map showing the current network (essentially all the major interstates and other limited-access freeways) and the new highways. In California, they've added 395 up to about Lee Vining, 99 north of Sacramento, 101 between maybe Santa Rosa and Willits and also maybe San Luis Obispo to Santa Barbara, and also 86/78/111 running from indio down to El Centro.
395 and I imagine the others are often multi-lane divided with at-grade crossings, much like the Florida highways where Brown and Brenner died thanks to A/P, so opening up Supercruise to these same types of roads will allow a direct comparison between it and A/P as to how well they can detect, recognize and act when dealing with crossing traffic. Cadillac has been far more conservative to date than Tesla as to how much risk they are willing to put their customers in, so I suspect S/C will be able to deal with these situations far better than A/P has so far, but we'll see. The much smaller fleet of S/C-equipped Cadillacs compared to the number of A/P-equipped Teslas out there means that it will take Cadillac quite a while to generate enough miles on these roads to get statistically significant data.
