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.

GM recalls 83,572 SUVs for ignition switch issue

General Motors is recalling 83,572 SUVs from the 2011 and 2012 model years over a potential ignition lock actuator issue. In affected vehicles, the actuator isn't the right size, which could cause the ignition to get stuck in the "Start" position, and then either due to a jarring event or a "cool interior temperature" the ignition could switch back to the "Accessory" position. Doing so would cause a loss of power assistance and the airbags might not deploy. This is a different ignition issue than the one that's been ongoing for the past year. GM said it expects that less than 500 vehicles suffer from the problem, but that the pool could include vehicles from 2007 through to 2014 that have already been fixed, but with defective parts. The 2011-2012 SUVs included in the National Highway Traffic Safety Administration notice: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. GM will notify owners and dealers will inspect the ignition lock housing to see if it needs a free replacement. RECALL Subject : Ignition Lock Actuator may Bind Report Receipt Date: DEC 30, 2014 NHTSA Campaign Number: 14V827000 Component(s): ELECTRICAL SYSTEM Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position. CONSEQUENCE: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury. REMEDY: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696 for the original equipment, and 14912 for the service replacement parts.

Seventies super-salesman challenges new car-sales record

Some of the fondest memories from my youth were the Sunday afternoons spent walking between rows of new and used cars. This preceded the advent of widely available internet, so the cars didn't sell themselves online: A tentative buyer had to come see the cars in the metal, with old-school salesmen taking well-earned smoke breaks after putting someone behind the wheel of a new Saab 900. All-inclusive subscription services were unheard of. If you open a Guinness records book and look up car salesmen, you'll find Joe Girard. The definitely old-school Detroit salesman regularly sold over 1,000 new cars per year, with a particular high point of 1,425 cars in 1973 guaranteeing him a mention in the Guinness book. To reach that kind of sales figure, you had to be a pretty special salesman, and Girard was. He didn't take breaks unless absolutely necessary, and even his lunch hours were dedicated to selling more cars instead of shooting the breeze with other sales persons. By 1977 he was worn through, having sold over 13,000 cars in his career, and his physique couldn't take it anymore. He's been a motivational speaker since. Now, 44 years later, a Dearborn, Mich., Cadillac and Chevrolet salesman named Ali Reda has reportedly broken Girard's record. The books at Les Stanford Chevrolet Cadillac say Reda sold 1,530 new cars and 52 used cars in 2017, averaging 130 vehicles per month. But after Girard, 89, heard of the sales record, he called his attorney, not letting his record be broken without a fight — or at least an audit. The Dearborn dealer isn't too concerned about Girard's doubts, at least according to Gary Stanford, whose father founded the dealership. "It's very official, trust me," said Stanford to the Detroit Free Press. "Ali is the hardest worker I've ever seen. And if someone doesn't believe the data, well, they're more than welcome to consult with GM. It's all there in black and white." What Girard doesn't get is that Reda was honoring him with the accomplishment. "I read his book, 'How to Sell Anything to Anybody,' and it said it would teach you how to become the best," said Reda, who at age 44 was a newborn when Girard hit his peak. "He's an absolute legend in the industry. Your whole career, you're chasing his name.
