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.

Dodge Challenger SRT Hellcat vs. Chevrolet Camaro ZL1 in latest Head 2 Head

"Olympian" is one of the terms we use to signify the greatest height, the seat of the gods. Yet Mt. Olympus is the second-highest peak in the Balkans ranges, overshadowed by the crest at Musala in Bulgaria's Rila mountains. Both great heights, but one is a little higher. That's how we get the Olympian Chevy Camaro ZL1 pitched at the Musalic Dodge Challenger SRT Hellcat in Motor Trend's latest episode of Head 2 Head. The side-by-side spec sheet is filled with farcical numbers. For the ZL1, that's a 6.2-liter V8 with 580 horsepower, 556 pound-feet of torque, a 4,051-pound curb weight, 0-to-60 miles per hour in 3.9 seconds, a quarter-mile time of 12.2 seconds and a base price of just $57,800. Opposing that, the Hellcat wrings out its 6.2-liter V8 for 707 hp, 650 lb-ft of torque, weighs 4,449 pounds, does the quarter in 11.7 seconds and has a base price of just $60,990. Except in the case of the Hellcat, when Motor Trend put it on the dyno the machine spit out a reading of 672 hp and 606 lb-ft at the wheels. If there's a 10-percent driveline loss through those beefed-up internals and heavy-duty eight-speed transmission, that means the Hellcat is actually rated at about 750 horsepower and 700 lb-ft. But once they get put on a closed-off strip of coast road in Northern California, there are only a few strands of hair between their respective performances. That's not the case for they sensations provide; host Jonny Lieberman calls one of them, "One of the most incredible cars ever made," and says, "It changes everything." Watch the video above to see who got the verdict and how. Related Video:

Chevy Volt sales drop in June, Nissan Leaf inches upwards

Different month, same story. That's the gist of the monthly US sales numbers from the Chevy Volt and the Nissan Leaf. These were the first two mass-market plug-in vehicles to go on sale in the US and we've been comparing their sales numbers for what seems like ages now. So far, the 2014 tale of the tape shows the all-electric once again trumping the plug-in hybrid. The last time the Volt outsold the Leaf was in October 2013. Chevrolet sold 1,777 Volts in June. That was good enough to be the Volt's best sales month of the year, but it's down 34 percent from the 2,698 units sold in June 2013. In fact, it's on par with the 1,760 Volts sold in June 2012. Given the steady sales, General Motors might need to push up the release of the next-gen Volt to gin up excitement, especially if it also offers some of the things that current Volt drivers say they want improved: more range, a lower price and a fifth seat. GM also said it sold 85 Spark EVs in June, an increase of 215 percent over June 2013 Nissan sold 2,347 Leafs last month. The good news continues for Nissan, which says it sold 2,347 Leafs last month. That's an increase of 5.5 percent over 2013 numbers and makes 2014 the best June ever for Leaf sales. Let's credit Texas. Toby Perry, Nissan's director of EV sales and marketing, said in a statement that, "Since the Texas state incentive went into effect in May, we've seen a big jump in Leaf sales in the Austin, Dallas and Houston markets. Our dealers are telling us that they saw more traffic in their stores, and they had their best Leaf sales performance in the last weekend in June." Even with that increase, Atlanta remains the top Leaf market. Nissan has sold 12,736 Leafs in the US so far this year; Chevy 8,615 Volts. Our detailed monthly sales write-up of green cars in the US, including plug-in vehicles, hybrids and diesel cars, is coming soon. For now, we invite you to discuss these numbers in the Comments.
