First of all - the guy riding the motorcycle walked away from the crash, he was wearing a reasonable amount of safety equipment but still suffered at least some road rash. The driver who turned in front of him did not stop and left the scene.
Here is the video: (sorry for my super crappy editing skills and poor vantage point)

The accident occurred at 36th Street at 19th Avenue S.E. at approximately 3:20PM today. A northbound vehicle, which appears to be a Maroon or Burgundy 2006-2007 Toyota Highlander turned left in front of a pair of southbound motorcycles and the front motorcycle crashed as a result of this. I was only a witness to this accident and was not directly involved but when I learned that the driver left the scene I was furious and wanted to help. We have already identified the Associated Cab in the video and that information has been passed on, and the yellow cab driver following the motorcycle stopped to offer help.
I have asked the rider's permission to post the video here. Let's not turn this into a "well he should have..." type thread, I'm sure he is already replaying this in his mind and is beating himself up over any little thing he maybe could have done.
If anybody has any information that would help identify the driver in this video please PM me directly or contact the Calgary Police. I have been in touch with both the rider and the police officer who is handling this incident and will pass on any information that is provided. I also posted this video over on the Calgary subreddit to try to get some additional exposure.
