Yay debate time!
You can't pin the blame on the biker....
If someone had opened there door, would you blame the driver of the car/passenger or the biker for driving through the traffic? - Correct answer is the driver/passenger of the car as they should of looked.
If there was no traffic, and that lady did the exact same thing, just ran across the road and didn't look, would you blame the biker for hitting her? - It would be her fault for not looking, however there would be more room for the biker to maneuver out the way.
As for him going way to fast, hardly....it's stationary traffic, it's going to look faster than it was. Any slower and he would wobble/lose balance and probably nudge a car.
IMO he wasn't riding recklessly and she just didn't look.
I'm not a biker, there are many scenarios where they **** me off, but I'm afraid this was just an unlucky circumstance.
edit - To be fair did just re-watch it, the first time, I didn't spot her, was wondering when someone was going to walk out. 2nd time was much easier to spot. Depends on the position of the camera as to his eye level etc. If his eye level was same with the camera, then he's a dumbass for not spotting her, but she's still a dumbass for not looking.
