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.

Minivan Comparison | Sienna vs Odyssey vs Pacifica vs Sedona

The minivan segment is fresher than it's been in years, possibly decades. The 2021 Toyota Sienna is a completely redesigned model with a bold new look and standard hybrid powertrain. Both the Honda Odyssey and Chrysler Pacifica were refreshed for 2021 with updated styling, upgraded tech, and in the case of the Pacifica, newly optional all-wheel drive. Only the 2021 Kia Sedona soldiers on without changes; it's still a solid van despite its advanced age and relatively few people buying it.  Usually when we put a comparison like this together, we have to pick and choose which vehicles to include (mostly because we can't do some 15-car spreadsheet without utilizing 4-point font). In the case of minivans, there are only four. That certainly makes it easier to research and cross-shop in person without worrying that you might be missing out on something. It also makes it a bit easier to go beyond the usual spreadsheet and dig a little deeper than normal into the competitors. Let's take a brief look at each. 2021 Toyota Sienna The Sienna is completely new for '21 after going a decade with only updates. Its exterior style is more expressive than before, but it's the new cabin that really impresses — it's far more car-like in appearance, but still offers the expected amount of abundant storage and functionality. Mechanically, the big news is that every Sienna is now a hybrid. Though down a bit on power compared to everything else, its 36 mpg combined (or 35 mpg with all-wheel drive) crushes everything but the Pacifica plug-in hybrid. This exceptional fuel economy and its far-sliding, big-kid-friendly second-row seats are its main selling points, but in every other respect, it's fully competitive.  Read our full 2021 Sienna Review 2021 Toyota Sienna View 41 Photos 2021 Chrysler Pacifica The Pacifica gets its first comprehensive set of upgrades since it was all-new for '17. The front end has been restyled, all-wheel drive is now an option and there's a new Pinnacle range-topping trim. The big news, however, is its technology offerings. Every Pacifica now comes standard, as the Odyssey and Sienna do, with a comprehensive array of driver assistance technologies. Every trim also gets Chrysler's latest UConnect infotainment system with a larger, 10.1-inch touchscreen and wireless Apple CarPlay and Android Auto.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.
