Unrealistically small? The example given was a child retrieving a ball. Even if they aren't completely under the vehicle as in the cat's case, the risk remains real nonetheless. It could've been a typical 7-year-old's head or arms under that rear tire instead.

Sorry Ms. Lovejoy, but I fail to see the harm in singling out Waymo here. It's an automated vehicle that purports to be intelligent, so when it kills a pet in a fashion that's plainly preventable, and elements of that scenario can translate to human children, it seems worthy of discussion.
