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.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Corvette Stingray gets optional Z06 components

If you've got a Corvette Stingray in the garage and have been tempted by some of the upgrades incorporated into the Z06, but can't quite bring yourself to trade up, Chevy has got some good news for you. The Bowtie brand has announced a series of performance parts derived from those in the Z06, but applicable to the base Stingray. The list of parts includes new cooling elements, prop shafts, brakes, suspension components, and underbody braces. They can all be fitted to Stingray models with or without the Z51 performance kit, and promise to raise the Corvette's game if not quite to Z06 levels, then closer to them. And for Z06 owners interested in gaining a bit more advantage, Chevy is offering a new Level 3 aero kit as well. The parts were demonstrated on upgraded 'Vettes at the Ron Fellows driving school at Spring Mountain. The school is also serving as technical partner and the track as the location for a new spec racing series built around the C7 Corvette. Dubbed the Michelin Corvette Challenge, the calendar is composed of fifteen half-hour races held in pairs over eight weekends, all on the six-mile circuit near Las Vegas. The cars to be used in the series will be close to showroom stock and feature many of the new Z06-derived upgrades, with Michelin racing slicks for dry weather and Pilot Super Sport tires in the wet. Perhaps most compelling of all will be the payment plan that will allow participating amateur racers to pay in installments across the season and take home their Corvette after the season's conclusion in December. New Z06 Parts Enhance Corvette Stingray Performance Broad range of chassis, suspension and aero components enhance capability 2015-11-02 PAHRUMP, Nev. – Chevrolet today and drivers from the Ron Fellows Corvette high-performance driving school at the Spring Mountain track demonstrated Stingray models enhanced with components from a new lineup of Z06-based performance parts. They're designed for 2014+ Stingray models, including Z51-equipped cars. "We've selected specific components from the Corvette Z06 and engineered them to fit the award-winning Stingray," said Jim Campbell, Chevrolet U.S. vice president of Performance Vehicles and Motorsports. "These Z06 parts enhance the handling, braking, cooling and downforce performance of the Stingray." Ron Fellows, champion Corvette Racing driver, collaborated with Chevrolet Performance engineers on the all-new portfolio.
