US teens ignore laws against texting while driving

With momentum building in Washington for all 50 US states to outlaw text messaging behind the wheel, there is evidence that the key demographic targeted by such legislation, teen drivers, will not pay much attention. At least one major study has found that, with mobile devices now central to their lives, young people often ignore laws against using cell phones or texting in the car. The number of text messages is up tenfold in the past three years and Americans sent an estimated 1 trillion in 2009. Some police agencies, while strongly in favor of such mandates, say its tough for officers to enforce them.
