IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.

GM drops diesel engines for 2020 Chevy Equinox and GMC Terrain crossovers

GM is officially discontinuing the diesel engine in the Chevy Equinox and GMC Terrain for the 2020 model year. The 1.6-liter turbodiesel was always an oddball of an engine in the compact crossover segment, and now the experiment has come to an end. The Car Connection initially reported the news, and a GMC spokesperson, Stuart Fowle, confirmed it to us this morning.  “A huge majority of our Terrain customers have opted for one of our two gas engines," says Fowle. We canÂ’t say this eventuality comes as a massive surprise, as we saw news from couple of months ago that GM was dropping all-wheel drive from the diesel-powered cars for 2020. Low demand was cited as the reason for that cull, and itÂ’s the same for the little GM crossovers this time around, too. These vehicles were the only ones powered with a diesel engine in their class, but thatÂ’s going to be changing. Just as GM is going away from the diesel, Mazda is finally bringing its diesel to market in the CX-5. YouÂ’ll only be able to get that engine in the most expensive ($42,045) trim level, combined with all-wheel drive, though. The cheapest Equinox diesel starts at a comparably low $30,795. ThatÂ’s a $2,400 upcharge over the base 1.5-liter turbo four-cylinder, and the value is questionable. Mileage is better, but diesel fuel is more expensive. Towing capability didnÂ’t increase over the base engineÂ’s 1,500-pound capacity, but the extra torque around town was nice. As diesels go in the U.S., this one was rather rough and noisy, possibly contributing to some turning their noses up after a test drive. Perhaps another reason for its demise was that the much quicker 2.0-liter turbo Equinox was only $100 more than the diesel. This engine offered significantly better towing at 3,500 pounds, too. You can read all about what we thought of the diesel in our first drive review here, but the 2019 model year is the last one if you had it on your shortlist.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.
