I know all of you readers are just clamoring for an update to this story, where the young man's mother refused to wear her seatbelt. Fortunately after a few days, we were able to remove his breathing tube and he woke up. He was eventually able to eat and walk, and I discharged him to a rehabilitation hospital late last week. His brain is mostly functioning normally, though he does have violent outbursts frequently. He should make a full recovery.
Update #2: His mother is still an idiot.
