The auto and “tech” capitalists are peddling the idea that putting voice command electronics in cars is all about safety, because it allows drivers to keep their eyes on the road. It is, of course, horseshit.
According to Automotive News, the research turns up the usual reality:
Car companies have turned to voice controls to cut down on distracted driving. But systems such as Apple Inc.â€™s Siri electronic assistant, which automakers started installing in vehicles in 2013, may be as mentally taxing as the buttons and knobs they replace, research released today by the AAA Foundation for Traffic Safety suggests.
The companies have turned to things like this not for safety, but because they are highly profitable add-ons. Anyhow:
For the AAA-commissioned experiments, conducted by researchers at the University of Utah, test subjects in a driving simulator used Siri to send text messages, post updates on Facebook and modify their calendar appointments. The test subjects averaged 4 points on a 5-point scale used to gauge mental strain while using Siri — a heavier workload than experienced when talking on a handheld cell phone or changing the radio. Three virtual crashes took place in the driving simulator during the experiments. Two of them occurred while using Siri.
David Strayer, the University of Utah psychology professor who led the research, recalled watching footage of one of the crashes, in which the test subject rear-ended an abruptly stopping car. He described it as a textbook case of â€śinattentional blindnessâ€ť — the driverâ€™s eyes â€śwere looking out the windshield, her hands were on the steering wheel, but she was taken aback completely by that vehicle,â€ť he said. â€śThe push to voice-based technology acknowledges that people need to keep their eyes on the road,â€ť Strayer said in an interview. â€śOur research suggests thatâ€™s not enough. You need to be paying attention to what youâ€™re looking at.â€ť
Undoubtedly aware of all this from the get-go, the car capitalists have their excuses ready to roll, though it’s all but certain that nothing serious will ever be done by the purchased political system:
â€śThis study focused on a very narrow aspect of distraction: cognitive load,â€ť Wade Newton, the spokesman, wrote in an e-mail. â€śBecause the study did not address either visual or manual distractions, the results tell us very little about the relative benefits of in-vehicle versus handheld systems or about the relationship between cognitive load and crash risks in the real world.â€ť
Annalisa Bluhm, a Chevrolet spokeswoman, said that the University of Utah research used Cruze and Impala sedans from model year 2013 that were equipped with older, less sophisticated voice recognition systems. She said GM still believes hands-free controls are safer than using a cellphone behind the wheel, and that it is working hard to improve those systems.
Improve, not remove, of course.
