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.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

Book by Cadillac is like a streaming service for cars

Cadillac is launching a subscription-based service that gives users access to most of its models for a flat fee of $1,500 a month. Called Book by Cadillac, the program starts in February in New York City and its surrounding areas. Cadillac's goal: attract users who want flexibility without the costs and commitment of ownership. The monthly fee is steep, but Cadillac argues it's competitive with the cost of leasing a well-equipped luxury car. It also includes maintenance, taxes, and insurance fees. The Book service can also be stopped at any time, which frees users from any payments. There's no restrictions on mileage, though users pay for gas either by filling up the car when they're done with it or through a Caddy concierge who bills their account. Cadillac will deliver and pick up the vehicles from the user's choice of location via a white-gloved driver. Users can change vehicles up to 18 times per year, and they can be reserved with a mobile app. The theoretical goal is a Book user could head to the airport in New York in a Cadillac and reserve another one for their use in Los Angeles. Cadillac ran a test program last year and decided to move forward with Book after receiving a positive response on the price and features. "The overwhelming result is this is something competitive," spokesman Eneuri Acosta said. The program features the Escalade, Escalade ESV, CT6, CTS-V, ATS-V, and XT5 decked-out in Platinum trim. Other vehicles, like the non-V-series ATS or CTS could be added if there's demand. Book by Cadillac starts in New York, but will expand to other unspecified markets. Related Video:
