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.

Your guide to vehicle subscription services

They might be extremely limited in scope because of location availability, but vehicle subscription services are a growing trend that most luxury manufacturers are jumping on. Plans are expensive, but you're paying for much more than just the car typically. We highlighted four of the larger plans with a few more listed at the end. Care by Volvo Volvo launched its subscription service last year with its brand-new XC40. It was the only vehicle available for a time, but subscribers can now get an S60 sedan as well. Subscriptions are for two years, with the monthly price including insurance, a concierge service, wear-and-tear item replacements and all maintenance. You'll be able to drive 15,000 miles per year with whichever Volvo you choose, and although there are no options to extend that mileage, you can swap cars after a year. Pricing for the XC40 is $650 per month in base trim, while an S60 can be as expensive as $850 for the R-Design. Volvo's plan is to offer more cars soon through the service, but it's relatively limited compared to others right now. Porsche Passport Porsche has two levels in its subscription service: Launch and Accelerate. Launch will cost $2,000 per month and give you access to the Cayman, Boxster, Macan and Cayenne. All of those but the Cayenne can be had in "S" trim as well. Accelerate is where the fun really starts. For $3,000 per month you can choose from a fleet of 911s, including the S, 4S, Cabriolet and Cabriolet S. If those aren't enough, you can also get the Panamera 4S, Macan GTS and Cayenne S. There are no mileage limits and you can change vehicles as often as you'd like. Also included in the price is insurance, repairs, detailing and any maintenance. It might be extremely expensive and limited to Atlanta only, but this subscription service is second-to-none for what you get. Audi Select Audi just launched its subscription car service, and it's offered in one version for a flat fee of $1,395 per month. For that you'll have access to five different cars including the A4, S5 Coupe, A5 Cabriolet, Q5, and Q7. Not a bad range of vehicles, but it would've been neat to see the recently updated A7 in there too. Maybe in time. Like the others, insurance and maintenance are wrapped up in the price. Audi is allowing for unlimited miles and two car swaps per month here. In addition to that, you'll get two days of free rentals through Audi's Silvercar rental agency should you go on a trip.

Cadillac CTS-V, ATS-V special editions celebrate IMSA titles

This was Cadillac's first year of competition for its DPi-V.R. Daytona Prototype race car in the IMSA Endurance Championship, and it brought home both the manufacturer title and driver title. To celebrate the occasion, Cadillac has created special editions of its fastest road cars, the CTS-V and ATS-V, and their defining features are stickers. Yes, the most unique part of these special Cadillacs is a decal package. But it is an attractive one, with white, gray, silver and red accents inspired by the race car. They're complemented by either a black or white paint job and red side mirrors. The rear quarter windows also get little stickers of the race car's silhouette. Though the stickers are the defining trait of these special-edition cars, they aren't the only features. The CTS-V and ATS-V each come bundled with an array of other features such as a sunroof, the carbon fiber exterior accent package, and a red and black interior that features red-accented carbon fiber trim and Recaro seats. Available as additional options are an eight-speed automatic for the ATS-V, a performance data recorder and a suede steering wheel and shift knob. The other neat tidbit is that, if those extra features are must-haves, the IMSA edition ATS-V is the way to go. The $72,190 price for the sedan is almost $2,000 less than an equivalent standard ATS-V sedan. The regular ATS-V sedan also isn't available with the red and black interior. The special-edition ATS-V coupe starts at $74,390, which is a little over $1,000 more than an equivalent normal ATS-V coupe. Unfortunately for CTS-V buyers, the IMSA edition model, at $105,730, is pricier than optioning up a regular CTS-V. So in that case, you'll have to decide whether the decals and exclusivity are worth it.
