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.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

Sunday Drive: Performance comes in many shapes and sizes

The Chevrolet Corvette has always stood out as a bastion of reasonably priced performance, and the latest 'Vette has that in spades. And while its expected starting price of around $120,000 certainly isn't cheap, it's an undeniable deal in the supercar world – remember, this thing'll do 210 miles per hour thanks to its 755-horsepower supercharged V8 engine. And did you get a load of that massive rear wing? Team Corvette's longtime foe, the Porsche 911, is similarly hellbent on ultimate performance. And as a reminder of how long the Corvette/911 rivalry has been melting tires we present the 1990 Porsche 911 as reimagined by Singer you see below. It's beautiful, it's green, and it's packing 500 air-cooled horsepower. You don't have to burn gasoline to go fast, as proven by the second-generation Tesla Roadster, which was revealed as a surprise late last week. Elon Musk says it'll be the quickest car in the world with a 0-60 time of just 1.9 seconds. And while you may not think of a semi truck when you think speed, the Tesla Semi can do 0-60 in 5 seconds flat unloaded, or in 20 seconds with a load of 80,000 pounds. Compared to today's crop of diesel semis, that's amazing. Continuing the truck theme, we present an artists rendering of what the next-generation Ram 1500 pickup may look like. Spoiler alert: Ram's mini-semi look is giving way to something much more modern. There may even be a first-of-its-kind split tailgate at the rear. And if you don't think the Ram 1500 has anything to do with performance, we should remind you that it's one of the cheapest ways to get a tire-shredding Hemi V8 engine in America. 2019 Chevy Corvette ZR1: All hail the 755-horsepower C7 king This is the first Porsche 911 to get Singer and Williams' 500-horsepower engine Tesla Roadster surprise reveal | 'Quickest car in the world' Tesla Semi Truck revealed: Here are the key details This could be the next-generation 2019 Ram 1500 2019 Ram 1500 spotted with split tailgate
