I don't know either but I do know that this collision has already got infinity times more press coverage and police attention than that time a wrong-way driver hit me on Howard and fled the scene. It's a problem with the whole AV discourse.
I can name two times in the last five years where, biking, I had a worse encounter than described (though I reserve judgment of fault until more details come out). Including one that required hospitalization, where the human driver decided to drive away.
The frustrating bit about AV discourse is that AVs are held against the standard of a perfect driver. Which I don't actually object to--all drivers should be compared to perfection. But it's enraging when people do so for AVs without comparing against human drivers, which, as everyone should know, fall far short of perfection. And with AVs we have the capability to iteratively improve them toward perfection, while there's no way to do the same with humans.
