Holy sh.. that must of hurt, atleast he somewhat saw it coming and started to lift himself off the bike before impact, might of helped him a little. Prime example why you always look in your mirrors when sitting at a light and keep it in first gear with the clutch pulled in for that quick launch if neccesary. I even use to watch in my mirror when sitting at a light and when I saw a car coming i'd tap my brake lights to give the guy behind me a heads up.
