An hour and a half of backseat footage inside self-driving Waymo

(actual course seems to have been in AZ)
Overall, this is quite impressive though.
This is not a "course" really, it is like a 50 square mile normal suburban area and the cars go where requested. There are controlled courses for testing such as the former military base that is closed off and has fake scenarios thrown at it.
But this is a service operating in normal neighborhoods.
That turn does seem to me like one of the tweaks you would add a little further on though. But I don't know because almost from day one it would need to be able to plot _some_ type of path there.
