Is hands-free just as dangerous? – Chris Lawrence reports

New apps may be posing a safety crisis on the road.

A new warning this morning that the very thing that was supposed to safely keep us connected, making hands-free calls while driving, may also be dangerous.

Chris Lawrence is in Washington with that story. He got a first hand look when researchers tracked his brain activity while he was on the road, driving and using new voice-to-text technology simultaneously. "You could be just as distracted with your eyes on the road and your hands on the wheel," Lawrence reports.

"The more I tried to multitask, the less my brain could do," he says, deteriorating driving performance.
