Thanks for sharing your harrowing story. I really think we should treat texting and driving at least as harshly as drunk driving, possibly even considering draconian measures like disabling phone access while in motion. I'm not typically a fan of draconian, totalitarian measures, but we clearly haven't evolved the cultural or legal framework to handle this.
I, myself, have been hit head-on twice on a motorcycle in the last 10 years.
The first time I was lucky, had a split-second of warning, and managed to escape any major injuries.
The last time, on 2013-10-13, I ended up with two broken wrists, a broken leg, and numerous contusions, scrapes, and scratches (initially, they also thought my ankle and nose were broke). It was four months before I could walk normally (the first three I couldn't walk at all). Because of how my arms were wrapped up (from my fingertips to the upper bicep), I couldn't bend them at my elbows and couldn't even wipe my ass for the first two afterwards. After the surgeries on my wrist, I was at least able to do that. I wasn't allowed to lift anything over one pound for the first six weeks.
I now have a titanium rod ("intermedullary nail") from my right hip to my knee, two steel plates in my left wrist, and one steel plate in my right wrist.
My life was forever changed -- and I was the equivalent of a helpless baby for almost three months -- all because an 18-year-old kid was texting on his phone and made a left turn in front of me at an intersection.
I hope your wife's wrists eventually stop giving her pain. Mine is sporadic and intermittent but will likely never go away completely, so they tell me.
