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.

The 2017 GMC Yukon XL Denali: Not just for the fertile set

I have a sis whom I've nicknamed "The Vickster." She is a beautiful Amazon, 6'1 on a good day and is the mom to a singleton. So why would my sis need to own a GMC Yukon XL Denali when she doesn't have a brood? Well to this I say, is there a written rule somewhere that states behemoth SUV's must be solely purchased by, you know, school-run moms? I think not! Even though the 2017 GMC Yukon XL Denali is tanker-sized and can swallow up to nine passengers, it has road presence and supreme luxury to boot which is a real draw for not just the fertile set. The Yukon XL Denali is an in-your-face kind of vehicle, and it was all in mine. The monolith has a presence, there's no denying, and even though it is big from every angle, it is far from odious. The stately looking ride has nicely defined slabs of metal, boxy proportions that make you look as it glides down the highway. Giving the Yukon XL my front-to-back once over, I liked its imposing mesh grille, nicely placed chrome accents and badges, riveting upsized wheels, and attractive high-intensity discharge (HID) headlamps and LED rear tail lamps. Once I settled into the cavernous and swanky realm of leather and mellow accent lighting that makes up the Yukon XL's interior, I then realized why "The Vickster" opted for this vehicle. The SUV's interior design is not overdone, no excessive bling to the point of blindness! Tasteful appointments on the Yukon XL include soft-touch leathers, aluminum trim, wood inlays, La-Z-Boy comfy seating in the first two rows (2nd-row power-release fold-and-tumble bucket seats); and thankfully, the non-gizmos overkill command center has large and ergonomically comfy controls. Space for a leggy crew is more than ample in the first and second rows. The SUV's available power folding, third-row fold-flat seats, however, are not exactly cut out for those who have gone past middle school as the seating is less bolstered and a little too close to the floor. Loved the wide and cushy center console that is not only spacious enough for hanging folders or a laptop but most importantly, it's elbow-friendly! Technology on the Yukon XL did not disappoint—particularly with the available built-in 4G Wi-Fi Hotspot for up to seven devices that kept me connected wherever I roamed.

What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.
