The autonomous vehicle is coming. Everybody says so. Or at least everybody who is paid to be optimistic about the fascist-corporate future of the Western World says so. Autonomous vehicles are already so safe that the only risks come from the imperfect humans surrounding them. The Times regularly fawns over the autonomous vehicle in the same vaguely insincere, Backpfeifengesicht-smirking way it concern-trolls about suicide-by-firearm. The problem, you see, is with all the people out there. They’re too stupid to drive a car or handle a gun and the only solution is for their betters in the $100M Manhattan condos and too-precious San-Fran Nob Hill homes to keep them dosed with soma and distracted with Centrifugal Bumblepuppy during the two and a half hours a day they’re not supposed to be either working in their ping-pong-table-equipped offices or sound asleep.

I’ve spent much of the past week reading about the near-perfect safety of the autonomous roadways of the future. As fate would have it, I spent much of the week before that driving a few hundred miles’ worth of fast back roads in an assortment of very fast sports cars. After spending some time considering what I’ve read and what I’ve been doing in a sort of holistic fashion, I’ve come to believe that the safety of autonomous vehicles, like many other technical and social issues in the United States, comes down to the story of the Country Mouse and the City Mouse.

In July, we learned the Pontiac Solstice and Saturn Sky may be at a risk of fire due to a blower motor issue that caused the recall of the Hummer H3. This may not be the only part that should be recalled. Many of GM’s roadsters are suffering from a defective sensor which could prevent the passenger airbag from deploying in an accident.

Volkswagen has spent over two years trying to block the publication of a research paper which reveals a key hacking vulnerability in many of their models as well as thousands from other manufacturers. According to Bloomberg, a team of researchers discovered the vulnerability in 2012 and notified Volkswagen in May 2013. Instead of working with the researchers to resolve the issue, Volkswagen argued that the paper would increase the risk of theft and sued them to stop the publication. Read More >

The fire-risk blower motor resistor harness has been recalled in the Hummer H3 and owners will start receiving repairs once parts become available. Owners of the Pontiac Solstice and Saturn Sky should be able to use the updated parts as well but will have to pay out of pocket as General Motors has not recalled them at this time. The Chevrolet Colorado and GMC Canyon also use a similar design and pose a similar fire risk but are slightly different than the recalled part due to having one less blower speed.

Hummer owners will most likely wait a few months minimum for the updated parts to get to their dealers to perform their free recall repairs. Colorado and Canyon owners may be waiting much longer — if they are recalled at all. The only silver lining for the Colorado and Canyon is that they use a similar resistor to the Toyota Tacoma and share a connector. The Tacoma also suffered from blower motor resistor issues and received updated parts along with a Technical Service Bulletin in 2011.

Last week, we learned General Motors was recalling the majority of their Hummer H3 and H3T models due to a fire risk from a melting blower motor resistor and harness. We also learned GM didn’t issue the recall until they were threatened by the National Highway Traffic Safety Administration.

A few days ago, Jalopnik’s Michael Ballaban pointed out the Chevrolet Colorado and GMC Canyon were also at risk due to similar components. These trucks may not be the last of the affected models as the Pontiac Solstice and Saturn Sky also shared many HVAC components with the Hummer H3.

Searching through the NHTSA complaints database and user forums yielded many examples of melted and burnt blower motor resistors and harnesses for the GM roadster twins.

When Maggie Dajani realized that the tire-pressure warning light was on in the van she’d rented to take six teenagers and their parents to a One Direction concert in El Paso, she took the van back to the rental company. A representative of the company, Star Limo, told her not to worry. She then continued to the concert. Shortly afterwards, the van blew two tires and rolled over. Several motorists helped drag the ten passengers out of the van, which was filling with smoke. The children went to the hospital with various injuries, and one of them reportedly received one hundred and fifty stitches as a result.

Now, the New Mexico Public Regulatory Commission has delivered a very, ahem, business-friendly verdict on the whole ordeal. Turns out that Star Limo is the beneficiary of a unique combination of regulatory conditions.

In a few weeks, at WOOT (the USENIX Workshop on Offensive Technologies — an academic conference where security researchers demonstrate broken stuff), a team from the University of Michigan will be presenting a lovely paper, Green Lights Forever: Analyzing the Security of Traffic Infrastructure. It’s a short and fun read. In summary, it’s common for traffic light controllers to speak to each other over a 5.8GHz wireless channel (much like WiFi, but a dedicated frequency) with no cryptography, default usernames and passwords, and well-known and exploitable bugs. Oh boy. And what can we do with that?

One of the Best & Brightest recently asked me to write about the history of automotive safety equipment. Today’s consumers ask how many airbags a car offers as standard equipment but in the 1970s the idea had a difficult time getting accepted, by both automakers and consumers. Read More >

Today, GM held a press conference regarding the Valukas Report on GM’s Ignition Switch Recalls, featuring CEO Mary Barra, as well as top execs like Mark Reuss and Dan Amman. The only problem was that the report had yet to be released, denying journalists the chance to question GM brass on its findings.

The House Energy & Commerce Committee recently released the documents GM submitted for investigation, which includes emails and internal reports documenting GM’s response to reports of their early Chevrolet Cobalt and Saturn Ion models inadvertently shutting the car “off” while driving due to an ignition cylinder that was, simply, too easy to turn out of the “run” position; and in the case of several accidents, allowed the ignition cylinder to rotate out of the run condition before or during accidents, causing the airbags to not deploy when required.

The documents, totaling 619 pages (some with repeat info), reveal just how deep seated “old GM” was in their cost cutting ways (Driving down supplier costs to the point of sacrificing quality, admittedly poorly designed ignition cylinder, and removing internal quality control on the parts), and just how blind sided “new GM” was during their investigations. It also confirms how suspended engineers Ray DeGiorgio and Gary Altman were involved in the ignition switch response, and fuzzy problem solving. Full text and an analysis of key documents below.
