I'm trying to see this from the driver's POV. If he really was asleep at the wheel, and as someone with sleep apnea, I can relate to the extreme fatigue (I've actually dozed off at red lights - nuts, I know), but if he really did fall asleep, he may have hit the cyclist and not noticed. The report I read said he also hit an embankment or wall or something. If it was right after hitting the doctor, he may not have noticed the impact with the bicycle, or he may have assumed it was from the impact with the embankment. IF the the larger impact woke him up, then I think it's plausible that he really didn't know that he'd hit a person.

Still, wouldn't that still make him guilty of gross vehicular recklessness resulting in bodily injury or something?
