You don't know what you're doing on Ambien. It's well documented. He has a history with this drug and I would be surprised if he wasn't taking it that night. My guess he was at somebody's house, took Ambien, was dreaming about golfing in California, 'woke up' and took off in his car like he was going to the course. This is not uncommon for things like this to occur while taking it. There are tons and tons of stories on this if you care to google them. And you can tell the dude looked more tired than messed up. Watching the video, it looked to me that he was in a highly sedated state. Out on his feet if you will...
