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.

2020 Cadillac XT6 Review & Buying Guide | Sneaking in through the back

The 2020 Cadillac XT6 is arriving late to the party, literally decades after some of its rivals. It's a new, three-row luxury crossover that serves as a much-needed, more-modern and less ostentatious family hauler than the Escalade (which is getting overhauled next year, by the way). The question about the XT6, then, is it fashionably late? The XT6 is indeed quite handsome and refined -- we thought it looked particularly excellent in one our test car's Red Horizon Tintcoat. There's a classic sophistication to it that evokes Cadillacs of the 1960s rather than the overwrought and borderline-tacky designs of other eras (including recent ones). We think the exterior design will age quite well, especially in light of some competitors. However, we're also not sure it's distinctly a Cadillac. Worse, the interior is drab, unimaginative, and blighted with unremarkable materials. A Volvo XC90 and Lincoln Aviator instantly look and feel more special, while a range-topping Hyundai Palisade isn't as far behind as the price gap would indicate. The driving experience also leaves something to be desired. Besides the ho-hum engine, the XT6 has neither the sharp handling of Cadillac's recent sedans nor the stately ride comfort one also might expect given the brand's past. Overall, the XT6 sneaks in through the back of the party rather than making a grand entrance; an unremarkable effort in a toughly contested segment. What's new for 2020? The XT6 is an all-new model and fills a gap in Cadillac's lineup. What's the XT6's interior and in-car technology like? Answering this question is all about perspective. In a vacuum, the XT6 interior seems nicely put together, its leather is soft and features are in abundance. The range-topping trim's gold carbon fiber trim is particularly interesting. If you sat in one after a Buick Enclave, the step up would be obvious. However, come from a Lincoln Aviator or Volvo XC90, to cite two excellent examples of the breed, and the difference is stark in terms of design and materials quality (there are too many hard plastics throughout). The XT6 quite simply isn't as cool, isn't as luxurious and doesn't seem to justify its price tag. At least features content is strong with six USB ports, wireless charging, Android Auto, Apple CarPlay and satellite radio all included along with a panoramic sunroof and various driver assistance technologies. Other brands nickel-and-dime you with this sort of content.

GM may have teased a whole group of electric vehicles

During GM's big CES press conference, the automaker highlighted a number of its upcoming electric car-related projects from delivery vans to the upcoming flagship Cadillac Celestiq. In the middle of it all, a collection of mystery cars sat in the background behind speakers. They were in the dark, lit only with their running lights, and while it's possible they're just generic filler cars or concepts, we think they could be future products. Our best shot of the cars together is shown above, and we can pretty easily identify three of the vehicles. In the center is obviously the GMC Hummer EV. On either side of it are Cadillacs. To the left seems to be the Lyriq crossover, and to the right is the Celestiq sedan. Two of these cars have production dates, and the third has been confirmed for eventual production, just without timing. This is why we think the rest of the cars are upcoming models. The next most easily identified car is on the near right behind the Cadillac Celestiq. It very clearly has a Chevy bowtie illuminated in the running lights. And looking closely, it appears to be a pickup truck. It's difficult to make out anything more than that. The nose does look a bit more rounded and swept back than the brick-like designs of the Silverado truck line. That also squares with what seemed to be the upcoming truck that appeared in the background of yet another GM presentation. GM previously said this electric Chevy truck will be a full-size model with up to 400 miles of range. That leaves us with three more mysterious models. Over to the left behind the Cadillac Lyriq are what appear to be a pair of crossovers. The one on the far left looks low, curvy, and possibly with a fastback roof. The one on the right is taller, boxier, and probably more of a full-size people hauler. It's hard to say much more beyond that. They could be new electric Buicks, which would fit in nicely with that brand's crossover portfolio, and would likely be highly successful in China, where Buicks, crossovers and electric cars are all rather hot commodities. As for the mystery car on the far right, it's quite a puzzle. We can at least rule out Buick and Cadillac, and GMC since it's definitely a car, and a rather small one compared with the other cars on display. That leaves Chevy, and possibly the autonomous division Cruise. We're leaning toward it being a Chevy, since the first Cruise vehicle is going to be a boxy pod of sorts.
