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 goofs again in latest Mirai fuel cell ad

In the "gotcha" culture engendered by social media and viral campaigns, it looks like Toyota got, well, got. The Japanese automaker is starting a campaign for its Mirai fuel-cell vehicle, and included a line about the fact that the car "breathes in air." Of course, all light-duty vehicles do that, as Jalopnik's Opposite Lock happily pointed out. Jalopnik added that even electric vehicles have an air intake for their heat exchangers. Oops. It looks like Toyota doesn't think this message is wrong, since the image is still up on the company's Google+ page. The Mirai can still lay claim to something that may impress the layman in that it emits only water vapor from its tailpipe. It's a pitch Toyota started making to Americans last November when the company said it would start Mirai sales this year in California. Toyota's charging an MSRP of $57,500 for those looking to buy the car outright or a three-year lease rate of $499 a month for 36 months (with $3,649 due at signing) for those to want to lease the car. Toyota also said in January that it would ramp up Mirai production to about 2,000 vehicles in 2016 from about 700 this year, as it expands distribution into Europe and the US. In the US, refueling the hydrogen will be free. Just like the chemistry lesson from Opposite Lock. Related Videos:

Subaru, Toyota refute reports of BRZ, 86 demise

After news broke of an anticipated Japanese report telling that the Toyota 86 and Subaru BRZ twins were not long for this world, both carmakers have denied the cars' successors have been canceled. Carscoops reports that both Toyota and Subaru have stated they are developing next-generation cars. As a Subaru USA spokesman told Carscoops: "We do not endorse this report coming from Japan's Best Car. ... We are moving ahead with a next-generation Subaru BRZ, but have no further details at this time." The website also reported a similar statement from Toyota. With the models getting long in the tooth and no test mules having been spied, doubts are not unwarranted — remember just how long Toyota teased the fifth generation Supra before its 2019 debut. More information is not yet available, or whether the two brands will still collaborate to bring the new-generation coupes to the market, but for Toyobaru fans this might be grounds to breathe a sigh of relief. That would also mean, that if the hinted MR-2 revival is based on solid ground, there will be a full "Three Brothers" Toyota sports car portfolio for sale in the next decade. With the Supra offered also as a four-cylinder in Japan, it will be interesting to see if Toyota will retain the 86's current, slight power advantage over the Supra's 197-horsepower variant or respect the status of the bigger brother.
