Clearly one of these two scenarios happened:

1. The waymo made a left turn into the space occluded by truck, seeing there was no vehicle behind the truck when committing to accelerating through the turn, but not seeing the bike in the adjacent bike line proceeding through the intersection.

2. The bike made a left turn from behind the truck into an occluded space, which would be suicidal.

While we can’t rule out the latter until we see video, the former seems much more likely. And that strongly suggests it accelerated too quickly. All the talk about the bike not stopping is beside the point — Waymo is supposed to be able to safely handle such situations.
