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.

Five awesome Lego car creations

Lego cars are among our favorite toys. They're fun for play, and if built properly, great to display. With that in mind, we've crafted a list of some of the best creations we've seen. Some are on sale now, while others are merely the work of fanciful enthusiasts. There are even a couple that you definitely cannot buy (we'll explain).
Our choices are diverse, including everything from a diminutive 1969 Chevy Corvette to a fullsize Ferrari Formula One racecar. These are just five projects that caught our eye - there are many more out there - so if you don't see your favorite Lego car on the list (or if you have your own creation), please tell us about it, in Comments.

GM lays off 450 at Lansing Grand River Assembly

General Motors will lay off 450 employees at its Lansing Grand River factory, The Detroit News reports, which is 100 more than the company said it'd be letting go last month. Lansing Grand River Assembly currently builds the Cadillac ATS and CTS, both of which have suffered sluggish sales, with the smaller sedan down 20 percent through last month and the larger model down 2.3 percent, The Detroit News reports. "We are adjusting plant production capacity to better align with market demand. Beginning in January 2015, the plant will operate on a single shift," a GM statement read, before explaining that not all the laid off Grand River employees will be jobless. Of the employees that have been laid off to make room for the single work shift, around 200 will transfer to the Lansing Delta Township factory, home of the Lambda-platform crossovers, GM's statement confirmed. The News expects this one-shift arrangement to continue until at least late next year, when the Alpha-platform Chevy Camaro transitions from General Motors' Oshawa, Ontario factory to Lansing. Cadillac President Johan de Nysschen said at last month's LA Auto Show, "It may not necessarily be permanent, a time may come when we've gained momentum and we can reinstate it. But for now, the adjustment to production capacity is in alignment with our plans for 2015."
