This sounds like a bad idea. I doubt people will respond with proper context, especially given that it will still be lacking in information. We already see people here making assumptions without sufficient evidence. Anything with cars and cyclists is always heated and we just get a lot of biases.
I think it is better that we distinguish that this type of event does not actually inform us about the safety of driverless cars nor does it provide enough information to adequately update our positions in either direction. It is void of so much context that it is essentially just noise. These things are hard to measure and even harder to make accurate decisions on. In an extreme case, it is possible for driverless cars to be "better than humans" at driving in the notion of accidents per mile (even normalized) while also being "worse than humans" in the notion of striking cyclists or pedestrians. "Accidents per mile" marginalizes the type of accident, but this would be important information as to making effective policy about when and where a driverless car can deploy (e.g. on average fewer accidents but most miles are on the highways. If there's a high rate of failure in detecting children in suburban settings, I sure wouldn't want that car driving in residential areas. The nuance matters). I think it's fair to say that the vast majority of us here on HN have a poor concept as to what the actual nuanced data says here and personally I feel like a video would only further sensationalize the event. I would not be surprised if a video were released which showed that Waymo could have not performed any better (without x-ray vision or omniscience) yet it also be used to further cases against them. I'm sure most people would make an accurate and reasonable conclusion upon seeing the video, but I still don't have faith that that means it wouldn't end up being sensationalized.
