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.

2018 Technology of the Year Award | We chat with Lexus about the LC 500h's hybrid system

Every year, Autoblog editors test dozens and dozens of the newest vehicles available, sometimes even before they're available. From those vehicles, we select the ones we think provide the most innovative technology in the industry. Then we pare the list down to the very best, test them again, and vote on our winner for Technology of the Year. This year, Lexus's multi-stage hybrid system — as tested in the LC 500h — came out ahead of the rest of the finalists. We chose the 2018 Detroit Auto Show to hand over the award to Lexus Group Vice President and General Manager Jeff Bracken. He was kind enough to sit down with Autoblog Senior Editor Alex Kierstein and Green Editor John Snyder at the Lexus stand to talk about the hybrid system, what it does, and what it means for the future of Lexus and Toyota. Check out the video above, and follow along for all our coverage from the 2018 North American International Auto Show in Detroit, where we are taking a look at all of the new cars and technology that we'll see in the near future. Perhaps the next winner of Autoblog's Technology of the Year award is sitting somewhere on the Detroit show floor.

Toyota promoting Mirai as if hydrogen tax credit never went away

At the end of December, the US federal government let the $8,000 tax credit for hydrogen-powered vehicles expire. Despite this little wrinkle, Toyota is still promoting the upcoming 2016 Mirai fuel cell vehicle as a car that will cost under $50,000. In some cases a lot less, since it may also qualify for a $5,000 incentive in California. The car has a $57,500 MSRP, but Nihar Patel, vice president of North American Business Strategy for Toyota Motor Sales, spoke at the 2015 Washington Auto Show last week, and said that the Mirai could cost $44,500 in California. You can see this in the video at around minute four. Toyota knows that the federal incentives have expired, since the real news from the show was Patel's public request to the federal government that the $8,000 tax credit be extended. "We think that the federal credit expiration last year puts [hydrogen] customers in a fairly disadvantageous postion," he said. Plug-in vehicle buyers can still get up to $7,500 tax credit and, "we believe that this inequity needs to be fixed," he said. You can see this in the video at minute 10:20. Toyota said including both the after-incentives price and the call to reinstate those incentives was intentional since it shows a discrepancy between hydrogen and plug-in vehicles in the eyes of the feds. We asked Toyota's director of Energy and Environmental Research, Technical and Regulatory Affairs, Robert Wimmer, for more details on Toyota's request. "[The Mirai] being a ZEV and battery electrics also being ZEVs, we just want to make the playing field as level as possible," he said, adding that any extension would last "for the run of the vehicle," which would be three years. He admitted that the extension might only be for one or two years, if it happens at all. (A Toyota spokesperson clarified to AutoblogGreen that the Mirai program will not end after three years.) And that's the problem. "The tax process is difficult to predict," he said. "The two challenges we have now are that both houses of Congress are Republican and also that there has been talk for a while about comprehensive tax reform. If that moves forward, then extenders would probably be put on the back burner as comprehensive tax reform is discussed." Wimmer would not reveal any details about how Toyota is pressuring the government to act, only saying that Toyota's has people lobbying up on Capitol Hill.
