> On the occasions I've felt I needed to glance at my phone while driving, I've held it up and in front of me so I still had peripheral vision of the road. People using their phone and doing so from their lap or console, not to mention actually interacting with the phone... I can't even.... I'm not sure if it really matters that much. Humans are very bad at paying attention to more than one thing. It's the attention that really matters, not so much the vision. Besides, peripheral vision essentially just tracks movements, and traffic is always moving regardless. I suspect that if there is a difference at all, it will be smaller than you'd expect.
