Today, millions of American drivers take traditional driver absent-mindedness to new heights. Behind the wheel, they're talking on cellular phones, sending and receiving pages, checking sports scores on personal digital assistants and even sneaking a glance or two at television, according to the Associated Press. Though the much-maligned cell phone gets the headlines for stealing drivers' glance time and causing abrupt lane weaving, experts say it's the mere tip of the iceberg, according to AP. And that is raising new fears among an array of authorities from lawmakers to insurance companies of a spate of new road crashes as more people literally are driven to distraction. Nationally, officials believe up to 30 percent of crashes are caused by driver distractions that include mobile communications devices, according to AP.
