Not that I want to get into an A&S pissing match but you can easily take your statement and switch the words driver and bicyclist. They were obviously at the intersection at the same time, the difference was probably a split second and you will never know who was there "first" or if it was even measurable. Also, to assume the driver was going even more than what they claimed is at best cynical.
Now cz has a good point about yielding to traffic from the right, that is definately true for normal crossing intersections. But this is a T intersection and I could be wrong but I always thought the vehicle going straight had the right of way over the vehicle turning.
Either way, this is pure speculation from everyone here. The article does not provide enough information and I will trust the investigation that we are not a part of will determine the sequence of events.
