Subject: Re: Study documents dangers of texting, dialing while driving Message-ID: <email@example.com> Per Fred Goldstein: >How much of this risk has to do with the awful design of modern >smartphones? I would agree that they're pretty bad. You'd think somebody would have come up with voice commands by now. Having said that..... I read that somebody somewhere (Canada?) did a study that suggested the main problem with cell phone use while driving was the nature of the conversation and not the hardware. With CB radio conversations there is an unspoken covenant between the participants: driving comes first. Pauses/gaps in the conversation are expected and understood. But with a cell phone conversation no such covenant exists. The person on the other end does not view my behavior any differently just because I am trying to negotiate 75 mph traffic while talking. I sense that and do my best to hold up my end of the bargain - which leads to the phone conversation taking precedence over controlling the vehicle. Seems to me like some people are better at multitasking/time slicing than others. While a passenger in a van commuting to work I have seen people reading a newspaper while driving. Not just quick glances - I mean reading that sucker. Personally, I think I'm somewhere over on the left of the bell curve so my cell phone use while driving gets restricted to furtive "I'm crossing the bridge, should be there within the hour...." type calls. -- Pete Cresswell

Right -- the person on the other end rarely is thinking that you have to drive. R's, John

Subject: Distracted Driving and Risk of Road Crashes among Novice and Experienced Drivers Message-ID: <email@example.com> Distracted Driving and Risk of Road Crashes among Novice and Experienced Drivers Sheila G. Klauer, Ph.D., Feng Guo, Ph.D., Bruce G. Simons-Morton, Ed.D., M.P.H., Marie Claude Ouimet, Ph.D., Suzanne E. Lee, Ph.D., and Thomas A. Dingus, Ph.D. N Engl J Med 2014; 370:54-59 January 2, 2014 DOI: 10.1056/NEJMsa1204142 >From the Virginia Tech Transportation Institute (S.G.K., F.G., S.E.L., T.A.D.) and the Department of Statistics, Virginia Polytechnic Institute and State University (F.G.) - both in Blacksburg; the Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, MD (B.G.S.-M.); and the University of Sherbrooke, Sherbrooke, QC, Canada (M.C.O.). Abstract BACKGROUND Distracted driving attributable to the performance of secondary tasks is a major cause of motor vehicle crashes both among teenagers who are novice drivers and among adults who are experienced drivers. METHODS We conducted two studies on the relationship between the performance of secondary tasks, including cell-phone use, and the risk of crashes and near-crashes. To facilitate objective assessment, accelerometers, cameras, global positioning systems, and other sensors were installed in the vehicles of 42 newly licensed drivers (16.3 to 17.0 years of age) and 109 adults with more driving experience. RESULTS During the study periods, 167 crashes and near-crashes among novice drivers and 518 crashes and near-crashes among experienced drivers were identified. The risk of a crash or near-crash among novice drivers increased significantly if they were dialing a cell phone (odds ratio, 8.32; 95% confidence interval [CI], 2.83 to 24.42), reaching for a cell phone (odds ratio, 7.05; 95% CI, 2.64 to 18.83), sending or receiving text messages (odds ratio, 3.87; 95% CI, 1.62 to 9.25), reaching for an object other than a cell phone (odds ratio, 8.00; 95% CI, 3.67 to 17.50), looking at a roadside object (odds ratio, 3.90; 95% CI, 1.72 to 8.81), or eating (odds ratio, 2.99; 95% CI, 1.30 to 6.91). Among experienced drivers, dialing a cell phone was associated with a significantly increased risk of a crash or near-crash (odds ratio, 2.49; 95% CI, 1.38 to 4.54); the risk associated with texting or accessing the Internet was not assessed in this population. The prevalence of high-risk attention to secondary tasks increased over time among novice drivers but not among experienced drivers. CONCLUSIONS The risk of a crash or near-crash among novice drivers increased with the performance of many secondary tasks, including texting and dialing cell phones.
