Having no memory of the event may not be so serious. I fell asleep driving a road construction camp half-ton pick-up back to the camp from Banff. On the highway between Banff and Jasper in the BC Rockies. Couldn't remember anything, except one thing, from hours before the accident until waking up in the hospital over a day later. Apparently i was traveling about 100mph, went off the road into a small drop, truck hit and flew about 100 feet. Head hit the windshield. About 8h after the accident a forest ranger found me lying in a ditch, four miles from the truck. Only memory was a vision of standing outside the truck at the scene of the accident looking at my slit wrist. Lucky the slit just missed that big vein, and that i had enough survival instinct to walk along the road.
I just hope Tiger's physical heals ok.
