2 or 3 years ago a teenaged girl in Texas was killed that way. I can't wrap my brain around it.
I've had a cellphone since the mid 80s (back when they were CAR phones). I had one of the earliest handheld phones, before there was such a thing as a smartphone. I'm not exactly a Luddite. But long before anybody told me to be careful, I was stopping conversations if I needed to enter a freeway, navigate a busy intersection, or anything other than just cruising down the highway. It's just not that difficult to say a quick, "Hold on." and PUT THE PHONE DOWN.
