I'm pretty sure it's the bus. Generally a already moving vehicle with a green light on straight road has right of way. The correct action for the autonomous vehicle (or a human driver) would be to wait for all traffic in the lane to clear (for example, after the previous light turns red and there is a lull in the traffic), then make it's way around the sandbags.
Here's my artists rending. The vertical lane is just the right hand lane, and is "wide", but still one lane. The bus is traveling "up" and the Google AV tries to manenouver around the sandbags blocking it's way. Thinking that it can get around in time, the AV starts moving to the left and crashes into the bus.
I guess the "one lane" aspect is the confounding variable, but since the autonomous vehicle was stopped, then it takes on the aspect of any other stopped vehicle on the side of the road (ie giving up it's right of way). Just like if you have a road where cars are allowed to park on the side of the road, those cars cannot enter traffic unless it is safe to do so.
Edit: Actually, I have no idea. Did a quick read of California's right of way laws, and couldn't find anything that jumped out that would cover this situation.
I'm actually really curious about this now. It's a "wide" lane, with room for 2 sets of cars. The AV itself went into the right hand part of the lane while other cars were still in the lane. Presumably the lane is wide for making right turns, otherwise basically ever car there is making an illegal right turn (and law enforcement probably would have already noticed that by now).
So either the AV broke the law first (by doubling up in a lane), or the bus had the right of way. I'm with the other commenter, why isn't it just an actual turn lane?
Also, if the bus is at fault here, then this would be an amazing place to commit insurance fraud. Just sit in the right hand part of the lane, wait for traffic to pass by, then drive back into the left hand portion of the lane right as a BMW/Mercedes/Ferrari/etc drives by.
I wonder about this too. If you are new to CA, at first it seems crazy how aggressive people are about splitting the right hand lane to turn right... who would have the right of way if the bus was already stopped at a light, but the AV split the lane to turn right and passed the stopped bus? I like the idea of splitting the right lane to make right turns, but IMO, if you've done so, you no longer have the right of way for traffic in that lane.
It sounds like this happened too close to the intersection for parking to be legal. If I see a car stopped on the right side of the road at an intersection signalling a r right turn, I don't assume it's parking, I assume that it's stopped for a pedestrian in the crosswalk.
I agree with you analysis. If the AV was stopped completely, then it should wait until there is an opening before resuming motion, just as a parked vehicle would do.
But, if the AV was not stopped, I think the bus is now at fault for attempting to pass a moving vehicle within its own lane, which is illegal (I hope).
I don't think there's any rule of the road saying you lose or gain right-of-way depending on whether your car stops. If you park the car, yes, or if you are stopped long enough that a reasonable person would think you were parked. But just coming to stop does nothing.
In this case, I think it all boils down to vague ideas about right-of-ways when drivers casually divide lanes.
