The research was led by David Strayer, a neuroscientist at the University of Utah who for two decades has applied the principles of attention science to driver behavior. His research has showed, for example, that talking on a phone while driving creates the same level of crash risk as someone with a 0.08 blood-alcohol level, the legal level for intoxication across the country.
In this latest study, he and a team of researchers compared the impact on drivers of different activities, including listening to a book on tape or the radio, and talking on a hand-held phone or hands-free phone.
The researchers compared how the subjects performed when they were not driving with two other conditions: when using a driver simulator and in a car equipped with tools aimed at measuring how well they drove. The researchers used eye-scanning technology to see where driver attention was focused and also measured the electrical activity in the brain.
Mr. Strayer said the results were consistent across all the tests in finding that speech-to-text technology caused a higher level of cognitive distraction than any of the other activities. The research showed, for instance, that the person interacting with speech to text was less likely than in other activities to scan a crosswalk for pedestrians. And that driver showed lowered activity in networks of the brain associated with driving, indicating that those networks were impaired by the interaction with the technology.
In a string of claims straight out of the old tobacco corporation playbook, the Alliance of Automobile Manufacturers lies about being “concerned,” obfuscates the issue, and, of course, finally excuses its members:
“We are concerned about any study that suggests that hand-held phones are comparably risky to the hands-free systems we are putting in our vehicles,” said Gloria Bergquist, the vice president for public affairs at the Alliance of Automobile Manufacturers in Washington, adding that carmakers are trying to keep consumers connected without them having to use their hand-held phones while driving.
“It is a connected society, and people want to be connected in their car just as they are in their home or wherever they may be,” she said.
What the AAM spokeswhore doesn’t mention is that built-in hands-free devices are just so many more parts to a car, each of which is a profit center. The overclass, you see, wants to sell these parts. And it will.
It’s mass murder for money, plain and simple. The corporate veil makes it all normal and natural.
The automakers aren’t likely to slow down development of the technology unless the law forbids it [cue sound of cats laughing], said Ronald Montoya, consumer advice editor for Edmunds.com, a research firm.
“They’re not going to pause based on this research,” he said.
