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.

Nissan not shuttering Leaf EV battery plants, at least not yet

The big news on the electric vehicle front today is that Nissan is considering slowing down EV battery production in the US and UK and source all of Nissan's big packs come from Japan. Nissan may also buy some batteries from the Korean company LG Chem. This is apparently causing dissent within Nissan, but it follows what Alliance partner Renault is doing in the hunt for 180-mile EVs. This change – officially denied by Nissan – raises a lot of questions here, since Nissan made a huge deal about building the Leaf pack in Tennessee a few years ago. In fact, the car's big price drop was due, in part, to localizing battery production. If the company is really going to give up on building the packs where it makes the cars, then does Nissan not see itself as being capable of producing an energy-dense battery cheap enough to compete with Tesla and its Gigafactory and GM (which, of course, has long worked with LG Chem on batteries)? Whatever Nissan decides, it needs to be ready to compete in a market that offers a $35,000, 200-mile car by 2017. "We have not taken any decision whatsoever to modify battery sourcing allocation." – Renault-Nissan's Rachel Konrad Nissan would not comment directly on the reported change, but Rachel Konrad, the Alliance's global director of communications and marketing told AutoblogGreen, "The Renault-Nissan Alliance remains 100 percent committed to its industry-leading EV program. This global commitment continues for the foreseeable future, and we have not taken any decision whatsoever to modify battery sourcing allocation. Nissan has no plans to impair its battery investments. Beyond that,we will not comment on speculation or anonymous sources, and as a matter of policy the Alliance does not confirm or deny procurement reviews." There's a point-of-view where it doesn't matter where the batteries come from if the resulting EV is competitive, price-wise. Renault CEO Carlos Ghosn, after all, said during a recent Twizy test drive that the battery is a means, and the objective is the car. In the end, Nissan is saying it has no near-term or medium-term plan to shutter plants in US or UK and CEO Carlos Ghosn says, "What's important to us is that electric car performance fully meets customer expectations." Whatever's going on, Ghosn has seen three top executives leave the Renault-Nissan family recently.

Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.
