Was Tiger Woods sleep-driving when he crashed?

An emailer writes:

I had a eureka! moment last night. Tiger was not awake when he crashed his car. This is why he was said to be snoring in the street by the neighbor in the police report. He probably is using ambien and "sleepwalked" the whole thing. His wife probably broke the window to attempt to wake him up, following him out of the house, but obviously being behind enough in time that he already had gotten in and started the car. This type of thing is a very common side effect of ambien. He can't sleep because his wife had already found out about the girlfriends.... I'm surprised I haven't seen this explanation offered by anyone.

Here's a news article saying he was sleeping and snoring in the street after the crash:

They found Woods apparently unconscious in the street, while his wife, Elin Nordegren, standing nearby. Woods was shoeless, in a T-shirt and shorts.

"He was actually snoring," [a witness] said.

Sleeping and snoring in the street after all that? You don't snore when you're knocked unconscious, do you? That sounds like a sleeping drug, which also explains how the highly skilled Woods could drive so badly.

Looking for that news article, I found this:

From Radar: "[Rachel] Uchitel told friends that she and Tiger liked to have sex while taking the drug Ambien. Uchitel told one pal, 'You know you have crazier sex on Ambien — you get into that Ambien haze. We have crazy Ambien sex.'" Readers: Is that a thing? We've witnessed people in an Ambien haze, certainly. But Ambien sex? This makes us feel old not knowing this.

Is it all fitting together now?

ADDED: The emailer was Elliott Althouse (no relation). And, in the comments, several people say that a person unconscious with a head injury might snore.
