Slightly related, I just finally was forced to upgrade from a 2010-era brick phone to a smart phone (they were turning the 2g towers off).
With my old phone, I could pretty safely check an incoming call or text without taking my eyes off the road for more than a second or so.
With me new phone, I can't even manage to unlock my phone without feeling like I'm going to kill someone.
I guess it makes sense that the rise of all the anti-cellphone laws coincided with the rise of smartphones. They are absolutely hostile to anything but undivided attention.
