It cost $6 million dollars to do the research, including setting up the video cameras in the trucks and track them for 3 million miles as they hauled items such as frozen food, furniture and other products around the country. Tom Dingas, director of the Virginia Tech Institute, one of the world's larget researchers in vehicle safety, said that texting while driving should be made illegal. Currently, it is against the law to text and drive in 14 states including Alaska, California and New Jersey. The huge increase in sending texts has made this a major problem. This past December alone, U.S. cellphone users sent 110 billion messages, a tenfold increase in just the last three years according to data from the CTIA, the cellphone industry's trade group. So next time you feel the urge to send a text message while you are driving, don't do it. Nothing you can say is worth increasing the chance of being involved in an accident by 23 times.
