Prayers continuing for a good outcome, sounds like your friend Jim is doing better than might be expected. Out of curiosty, is he left-handed? I have read that sometimes lefties brains have an unusual ability to rewire themselves.
Very sorry to hear all of this... I can not understand people, especially this texting while driving crap that's going on. Jim is just one of many because of this stupidity, again very sorry, my thoughts and prayers are with Jim and his family.
