it's obviously a guy...
well, that video kinda sucked, here's the entire version:

anyways, this was on digg a while back. Here's my translation (I was able to get a little more after, but i can't re-hear it here at work right now)
"From what I else I could hear; he also says (to the best of my ability)
[0:21]
[guy]You had a red (treh-ehmo, not sure what this word is), i had priority from over there
[she's says something and they exchange a few words, but not sure exactly what here]
[0:50]
[guy]i had green and came from here (point to his lane) and you with the red tried to kill me
[0:57]
[guy] from over here I had green!"
that's from the youtube video. another person on digg figured out that it was an olympics volunteer who got hit. in the youtube vid, you can see the car slam into the bike just in front of his knee
addendum: this was in Greece. If you've never been to a mediterranean country... well, they all drive crazy.
