I drive ALL DAY professionally, and in Anchorage I see this happening more often than not, in Midtown, Downtown, Muldoon, Hillside, Spenard, Turnagain, Mt. View, Fairview...any place I happen to be.  You rarely see it?  If you're driving all day, you must be multitasking.  I see a lot of texting and talking on the phone too.
