Without knowing what type of vehicle the first car was, it's hard to say how this played out. If it was a van or truck or something else that could've easily obstructed Cruise's LIDAR system or if the other vehicle stopped ahead of the crosswalk line, the SDC would've had little to no way of knowing that there was anybody in the crosswalk.
Can't know for sure unless Cruise releases the video to the public, which they're unlikely to do until the police do their investigation.
If your vision of the crosswalk is obstructed, you don't proceed through until it's unobstructed. That's true whether it's radar, lidar, or vision. Truck in the way? Pull up as far as you can safely see, then look and proceed if clear.
