text: Even the best drivers may be involved in a potentially life-threatening crash while trying to use their phone and drive. According to an NPR article on multitasking, when you are "Switching from task to task, you think you're actually paying attention to everything around you at the same time. But you're actually not. You're not paying attention to one or two things simultaneously, but switching between them very rapidly" (Hamilton). The article later goes on to state, "You cannot focus on one while doing the other. That's because of what's called interference between the two tasks." Based off of this information, it can be inferred the concept of interference is also applicable to using a smartphone while driving. If a driver is busy paying attention to their screen, there is no way they could also be paying close attention to the road.
