Although it is frightening to see another person driving on the road holding a smart phone in their hand looking at it, instead of the road, I can certainly understand the "why."
Modern technology has compacted absolutely everything in our lives into a little bitty box that can be carried in a shirt pocket .... everything.... everything from banking to communication to education to entertainment to employment!
Forget about the real reason (government conspiracy ... "they" are tracking you) as the underlining purpose for this technology, they've convinced us we need this stuff and in a way, and have succeeded by making it next to impossible to exist as a person without it.
Older generations still resist new technologies. Newer generations grow up with it and it's just a matter of fact of life, no big deal.
Bottom line: Modern technology is not going away, neither is the smartphone. Except, I am now wearing a wrist watch that can do almost all the functions that my smart phone can do now! Even more .... it monitors my "health".... talk about "big brother intrusion into my private life!" Yes .... that data is stored somewhere, and I certainly do not know where that is!
So, we can either accept the technology or continue to be frustrated over it.
Still, it does not give us any comfort when the distracted looney toon driving directly toward us isn't watching the road though because their attention is drawn toward some mindless TicToc video that a 13 year old posted about how marvelous it was he jumped off a bridge and only broke 1 leg!
