A short extract from the report highlighting why multi-tasking is a myth.

“Multitasking” is valued in today’s culture, and the desire for increased productivity makes it tempting for drivers to engage in tasks that are unrelated to driving. Drivers may believe they can safely do two things at once; however, a driver always must be prepared to respond to the unexpected. Under most driving conditions, drivers are performing well-practiced driving tasks. For example, experienced drivers automatically slow down when they see yellow or red lights, and activate turn signals when intending to make a turn or lane change. Staying within a lane, noting the speed limit and navigation signs, and checking rear- and side-view mirrors are also automatic tasks for most experienced drivers. People can do these driving tasks safely with an average cognitive workload, such as listening to music. During the vast majority of road trips, nothing bad happens, but that can lead people to feel a false sense of security or complacency when driving. People often think they are effectively accomplishing two tasks at the same time. It is possible to complete a phone conversation while driving and arrive at the destination without incident, but it is a misconception that the tasks can be done simultaneously and as safely as possible. 1. People do not “multitask.” Their attention switches back and forth between tasks very quickly.11 2. People cannot accomplish more than one cognitively demanding task in the same time frame with optimal focus and effectiveness given to each task. One task is primary and the other is secondary.
