Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

Cadillac Escalade gets $5,000 discount to ward off Lincoln Navigator

General Motors apparently isn't going to let early good reception for the redesigned Lincoln Navigator steal thunder from its own luxury SUV without a fight. It's offering a $5,000 discount on the purchase or lease of the Cadillac Escalade this month to any buyer who trades in a 1999 or newer Lincoln model, Bloomberg reports. GM spokesman Jim Cain told Bloomberg the incentive is being offered to keep prices competitive for the Escalade. The 2018 Navigator starts at $72,055, compared to $73,995 for the Escalade, but the outgoing version of the Navigator is selling for an average of around $53,000, compared with more than $80,000 on average for the Escalade, he said. The Escalade was the top-selling domestic luxury SUV in October and No. 4 in the segment, according to Motor Intelligence. It far outsold the Navigator, which last saw a refresh in 2015 and a full redesign in 2007. But Ford is hoping to gain back some ground with the new Navigator and updated Expedition, which also trails the Chevrolet Tahoe and Chevy Suburban in its segment. Bloomberg notes that one Morgan Stanley analyst estimates that GM owns a $2 billion annual pretax profit edge in the lucrative luxury sport utility segment. Our recent First Drive review called the new Navigator "far superior to its primary competitor, the Cadillac Escalade."Related Video:

Why Cadillac is willing to lose 43 percent of its dealers

Cadillac is offering about 400 dealers in the United States a lump sum of money to close down. That represents over 40 percent of Cadillac dealers in America. Offers start at $100,000 and top out at $180,000. The average offering is around $120,000. According to Automotive News, Cadillac chief Johan De Nysschen estimates it will cost the automaker around $50 million to close these dealers. Any dealer that chooses to remain open will have to submit to Cadillac's ambitious Project Pinnacle, which will divide dealers into incentive categories based on how many units they sell. "Every single Cadillac dealer will have the potential to earn significantly higher profits than they do today," says De Nysschen. Dealers have until November 21 to decide if they want to take the cash or submit to Project Pinnacle. A logical question: Why is Cadillac willing to spend $50 million to close down 43 percent of its dealers? First, GM's luxury brand has way more dealerships than it needs. Second, the 400 dealers with offers to shutter each sold 50 or fewer vehicles in 2015, representing just 9 percent of its sales volume in America. So, while closing these smaller dealerships may have a small initial impact on sales, it's not going to be a major hit to Cadillac.
