Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

GM recalls full-size truck, SUVs and vans over faulty shifter mechanism

Twelve different General Motors vehicles from the 2013 model year, up to 54,686 units in total, are being recalled over two potential issues with their steering columns. The models in question, all full-size trucks, SUVs or vans, are the: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe, and GMC Savana, Sierra, Yukon and Yukon XL.
The affected vehicles were built with a fractured parking lock cable or "a malformed steering column lock actuator gear in the lock module assembly." As a consequence, they could shift out of park without the brake pedal being applied or with the key removed or in the off position.
A bulletin from the National Highway Traffic Safety Administration indicates that the recall should begin on January 17. GM will notify owners, at which time they can take their vehicles to their dealers for repair free of charge. Have a look at the bulletin below for more information.

Teaching autonomous vehicles to drive like (some) humans

While I love driving, I can't wait for fully autonomous vehicles. I have no doubt they'll reduce car accidents, 94 percent of which are caused by human error, leading to more than 37,000 road deaths in the U.S. last year. And if it means I can fly home at night in winter and get safely shuttled to my house an hour-plus away — and not have to endure a typical white-knuckle drive in the dark with torrential rain and blinding spray from 18-wheelers on Interstate 84 — sign me up. Autonomous technology will also take some of the stress, tedium and fatigue out of long highway drives, as I recently discovered while testing Cadillac Super Cruise. AVs are also supposed to eventually help increase traffic flow and reduce gridlock. But according to a recent Automotive News article, as the first wave of AVs are being tested on public roads, they're having the opposite effect. Part of the problem is they drive too cautiously and are programmed to strictly follow the written rules of the road rather than going with the flow of traffic. "Humans violate the rules in a safe and principled way, and the reality is that autonomous vehicles in the future may have to do the same thing if they don't want to be the source of bottlenecks," Karl Iagnemma, CEO of self-driving technology developer NuTonomy, told Automotive News. "You put a car on the road which may be driving by the letter of the law, but compared to the surrounding road users, it's acting very conservatively." I get it that, like teen drivers, AVs need a ramp up period to learn the unwritten rules of the road and that a skeptical public has to be convinced of the technology's safety. But this is where I become less of a champion on AVs, since where I live in the Pacific Northwest we already have more than our share of overly cautious human drivers. Since moving here 12 years ago, I've found it's an interesting paradox that a region famous for its strong coffee, where you'd think most drivers would be jacked up on caffeine, is also the home to annoyingly measured motorists. As an auto-journo colleague living in Seattle so aptly put it: "People in the Pacific Northwest drive as if they have nowhere to go." If you drive like me and always have somewhere to go — and usually are in a hurry to get there — it's absolutely maddening.
