Its not nav screens, it's phones. people are freaking addicted to them. They cannot put them down, and they have to respond to every ding immediately.People are staring too much at that nav screen to pay attention to where they're going.
I've literally lost count of how many idiots I've seen watiching tv shows or videos driving down the road, weaving all over the place.
Then there's the hold the phone like a sandwich and use speakerphone all the time people driving around gesturing with their phones instead of driving.
PUT THE DAMN PHONE DOWN.
