This is the classic Suddenly Revealed Pedestrian test case, which afaik, most NCAP (like EuroNCAP, Japan NCAP) have as part of their standard testing protocols.

Having performed this exact test on 3 dozen vehicles (L2/L3/L4) for several AV companies in the Bay Area [1], I would say that Waymo's response, per their blog post [2] has been textbook compliance. (I'm not defending their performance... just their response to the collision). This test / protocol is hard for any driver (including human driven vehicles), let alone ADAS/L3/L4 vehicles, for various reasons, including: pedestrian occlusion, late ped detection, late braking, slick roads, not enough braking, etc. etc.

Having said all that, full collision avoidance would have been best outcome, which, in this case, it wasn't. Wherever the legal fault may lie -- and there will be big debate here -- Waymo will still have to accept some responsibility, given how aggressively they are rolling out their commercial services.

This only puts more onus on their team to demonstrate a far higher standard of driving than human drivers. Sorry, that's just the way societal acceptance is. We expect more from our robots than from our fellow humans.

Why? This is only true if they weren't supposed to be on the road in the first place. Which is not true.

In your experience, where do we find a credible source of info? Do we need to wait for the government's investigation to finish?

Remember Tesla's blog posts? Of course Waymo knows textbook compliance just like you do, and of course that's what they would claim.
