After reading about incidents like this, almost being taken out by a driver that was not paying attention, etc, I'm ready to install a video recording device on my bike and car. That way whenever crap like this happens there's evidence of who is in the wrong.
Did you try push starting it? My battery died one time from leaving the high beams on and fan running after it was off. Gave it a push start and rode the bike till the battery was good again.
