About 20% of drivers using Web behind the wheel, study says

Forget texting and driving or talking on the phone and driving: Those extremely dangerous habits are old hat. The new worry, says a survey released by State Farm this week, is what the insurance company cleverly calls "webbing while driving."

That means looking up Web pages, following driving directions, reading and composing e-mails, checking Facebook, and twiddling with smart-phone apps -- activities that require sustained concentration and multiple key presses. Among the 912 smart-phone users State Farm surveyed, more than 19% of them "webbed" while driving, the company said. For those who prefer fractions, that's one smart-phone-equipped driver out of every five.
