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.

Trucks, SUVs drive U.S. October new vehicle sales

DETROIT — Major automakers posted mixed U.S. new vehicle sales in October on Wednesday, though America's love affair with high-margin pickup trucks and SUVs remained in full bloom as larger, pricier vehicles fared better than passenger cars. Auto industry publication WardsAuto put the seasonally-adjusted annualized rate (SAAR) for light vehicle sales in October at a robust level of 18 million units. But after a long boom cycle, carmakers are still ill-prepared for the slight decline in sales anticipated for full-year 2017 and have taken too few steps to trim production, said Doug Mehl, a partner in consultancy A.T. Kearney's automotive practice. "When you make a new vehicle, you have volume assumptions tagged to it, and who wants to be the guy who says, 'I'm going to make less of this really cool model'?" Mehl said. "But eventually the market is the reality, and it's going to force companies one way or other here." General Motors GM reported a sales drop of 2.2 percent for the month, with consumer sales down 6.6 percent. But sales of high-margin pickup trucks, sport utility vehicles and crossovers all rose. GM also cut its inventory of unsold vehicles — a source of concern for the market — slightly. The automaker has worked to reduce its volume of excess inventory, including through significant production shutdowns in the third quarter. GM had said its inventory would rise in October. "We are heading into the fourth quarter with good momentum, thanks to a strong U.S. economy and very strong pickup and crossover sales," said Kurt McNeil, GM vice president for U.S. sales operations. GM slightly reduced consumer discounts as a percentage of average transaction prices to 13.5 percent, from 13.7 percent in the third quarter. Industry experts believe consumer discounts above 10 percent of the average transaction price are unhealthy as they erode resale values and are unsustainable in the long term. Consultants J.D. Power and LMC said last week that based on preliminary October sales numbers, discounts have exceeded 10 percent in 15 of the past 16 months. Ford The U.S. auto industry posted record sales of 17.55 million vehicles in 2016. New sales received a strong boost in September as consumers replaced vehicles damaged in southeast Texas by Hurricane Harvey the previous month. Full-year 2017 sales are expected to be slightly lower than 2016.
