More research into this contentious area has shown that our brains simply aren’t built for multitasking, yet alone performing other tasks while driving. Research done by neuroscientist Marcel Just of Carnegie Mellon University in Pittsburgh and his colleagues shows that using part of your brain for language processing reduces activity in the spatial regions used for driving. Since driving is the less-ingrained task, then that’s going to take even more of a hit.
But the reduction in ability isn’t limited to when you talk on the phone or with someone else in the car, but other things like attending to the radio, eating or dealing with kids or pets. Ok, so the research is there; now we as a society just need to accept it, and put the correct guidelines in place.
