I'm not quite sure that I buy this--I'd like to see some crash test footage or research data--but the American Automobile Association is claiming that the 10-and-2 steering wheel position ought be discarded. Modern technology, they claim, has made this ergonomic staple unnecessary due to power steering, and unsafe due to airbags.
The reason I say I'm not buying it: Given that airbags deploy from the center of the steering wheel, and your hands are on the periphery even at 10-and-2, wouldn't your arms still be blown outwards? How does a hand on the rim of the steering wheel make its way into the trajectory of the airbag?
