Hello, Siri? Please don't crash the car

Hands on the wheel and eyes on the road? You could still be distracted while driving. Voice-recognition software that many automakers tout as a safer alternative to handheld devices can still divert drivers' attention, a new study published by AAA found. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri. The technology is alluring because it allows drivers to do things like change the radio station or compose a text message without removing their hands from the wheel or their gaze from the road. But many of those tasks increase a driver's cognitive workload. Depending on the situation, that can be dangerous. "It's especially problematic, because you can be distracted and not know it," J. Peter Kissinger, president of the AAA Foundation for Traffic Safety, told Autoblog. "That's the nature of mental distraction. It's hard to appreciate. ... Often, you don't know you're distracted until it's too late." There's significant variation in the results of the study. Simple, single-task car commands for operations like changing the radio station caused minimal increases in workload, about the same as listening to an audio book. Composing information using speech-to-text technology was more burdensome, and using menu-based functions caused a high level of cognitive workload. Siri-based interactions posed the highest levels of distraction, according to AAA. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri, and two of the three simulator crashes they observed during the study of 36 participants came while the subjects were interacting with Siri. The subjects weren't looking at nor making contact with their iPhones during these interactions. "Common issues involved inconsistencies in which Siri would produce different responses to seemingly identical commands," the researchers wrote. "In other circumstances, Siri required exact phrases to accomplish specific tasks and subtle deviations from that phrasing would result in a failure. ... Some participants also reported frustration with Siri's occasional sarcasm and wit." It wasn't just the complexity of the task that caused variations in level of distraction – the variations could also be dependent on the particular make and model of the car being tested.

Toyota calling for independent, industry-wide Takata airbag testing

The initiative is still very new, and there's no set timeframe for this third-party testing to begin. With Takata's airbag inflator recall expanding nationwide soon, the scope of this safety campaign is only growing, and is set to affect millions of additional vehicles. Toyota thinks that it can help, though. The Japanese automaker has announced an initiative to get all of the affected companies to band together to fund independent, third-party testing of the faulty components. The goal of this work is to "ensure the inflators that require replacement are accurately identified and promptly fixed," according to Toyota. All of the data would be shared among the participating automakers to better understand the causes of these problems, which still aren't entirely known, and come up with the best way to repair the affected vehicles. "By combining our collective efforts behind a coordinated, comprehensive testing program, we believe we can achieve greater results. Together we will be better equipped to address this issue more rapidly for all customers," said Simon Nagata, President and CEO, Toyota Motor Engineering and Manufacturing North America, in the company's release. According to Toyota spokesperson Cindy Knight speaking to Autoblog, the initiative is still very new, and there's no set timeframe for this third-party testing to begin. The automaker's first step is simply getting the word out that it's looking for partners. She said Toyota "has spoken with colleagues in the industry" about setting up the independent evaluations and specifically said the company has already reached out to Honda and Ford about possibly working together on this. Honda also released a statement calling for similar third party testing, and when reached for comment about Toyota's proposal, Ford spokesperson Kelli Felker responded: "Ford takes the safety of our customers very seriously. We plan to join the proposed industry wide effort to investigate and develop solutions to address this critical issue. We look forward to discussing next steps with NHTSA and other automakers."

Construction of Lexus' first US assembly line underway

The ES is Lexus' top-selling sedan, but the Japanese luxury marque has never manufactured it outside of Japan. In fact, Lexus has never made any cars in the United States, one of its largest markets worldwide. But that's about to change.
Yesterday, construction began in Georgetown, Kentucky, on the first Lexus assembly line in America, the first concrete (or steel) step in a $360-million expansion of Toyota's plant in the Bluegrass state that will create 750 new jobs. The expansion was announced last April by chief executive Akio Toyoda at the New York Auto Show.
Once the new assembly line gets online in the fall of next year, Toyota plans on building some 50,000 units of the ES each year. Lexus sold a record 72,581 examples of the ES in the United States last year - 30 percent more than the previous year - so Lexus will either have to import some more from overseas or leave some buyers disappointed.
