Dr. David Strayer from the University of Utah identified a small subgroup of people who seem to be able to multitask extremely well. These "supertaskers" show little or no impairment when dividing attention between driving and talking on the cell phone. However, importantly, this only applies to a very small fraction of the driving population. The interview was conducted in 2009 by Mike Teske, beginning graduate student at the University of Idaho's Human Factors Psychology program.
