An earlier warningDecember 23, 2011Dear Sir,In November, 2006 you printed a letter (modesty prevents ...) noting that “A University of Utah study found that, when talking on a cell phone, whether hands-free or not, drivers showed levels of impairment similar to those of a person with a blood-alcohol level in excess of the legal limit”.Maybe if you gave all MPs a free subscription to the RG for Christmas they would get their breaking scientific news five years earlier than from whichever source they currently use.Yours making the call,ANDREW R DOBLEHamilton Parish
