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 ELR getting massive discounts, some up to $14,000

Well, that didn't go as planned. General Motors had marketed the Cadillac ELR extended-range plug-in as a premium version of the Chevrolet Volt with some Caddy refinements. Now, it looks like that premium, at least from a price standpoint, is shrinking. Shoppers in a number of states are reporting that GM and its dealers are discounting the ELR in order to move more off dealer lots. The issue is that few people are biting at the official price tag of about $76,000, so GM has started offering as much as $8,000 worth of dealer and customer incentives, Transport Evolved reports. More recently, dealers in states such as Florida, Texas and Maryland are offering discounts in the $12,000-to-$14,000 range, and that's before any federal and state plug-in incentives kick in. It's not difficult to guess why. Through the first half of the year, GM sold fewer than 400 ELRs. Last month, Caddy moved just 97 units, or about as many as Tesla sells of its Model S in a day. Perpahs recent spy shots that reveal a test ELR that appears to up the sportiness quotient, with touches such as larger wheels and brakes, will also help sales.

Driving the 2016 Cadillac CTS-V at the old Elkhart Lake road course

The placid community around Elkart Lake, WI, looks about as far removed from a glorious motorsport venue as you can imagine. A turn of the century downtown gives way to old-school resorts, beaches, and boat launches around the picturesque lake, with farms framing the rolling hills all around. But it was those very same meandering country lanes that gave birth to one of America's greatest racing circuits, some 65 years ago. Between the first race in 1950 and the opening of the dedicated Road America track in 1956, the roads around Elkhart Lake provided the setting for some great post-war racing. Competing on public streets was ultimately outlawed across the country, but not before drivers risked life and limb in the name of glory in the Wisconsin summer. Cadillac asked us out to the area recently, not to talk racing history, but to look forward at one of the most track capable cars the company has ever offered: the 2016 CTS-V. We got to drive the 640-horsepower beastie for an entire morning of hot laps at Road America, but unfortunately, we're not allowed to tell you about all of that right now. You'll have to wait until the embargo lifts on August 3, at which point we promise a full recounting of our adventure. Having the CTS-V for a full two days though, and in the spirit of the motorsport that imbues the air in Elkhart Lake, we took the Cadillac on a drive around the old 6.5-mile road course. Come for the new Caddy, but stick around to find out what the hell Wacker's Wend is. Cadillac Luxury Performance Videos
