I don't know what a good answer is, my recollection of those examples is no one else is slowing down so I need to go the same speed in order to not be rear ended and hope the car in front of me knows what they are doing. This feels pretty unsatisfactory. The speed limit is kind of interesting, occassionally see someone go the speed limit on I-5 but it's hard to maintain because there's always an eighteen wheeler going slower than that, and then it hits a hill, and then there's a cascade reaction where the slow lane hits 45-50 for an extended period but the fast lane is going 75-95, though just being patient and waiting in the slow lane isn't a big deal for a autodriving car, or 280 between San Francisco and San Jose with sections where it appears almost everyone is going 85 miles per hour (not sure why CHP doesn't just camp out there). I see Teslas in both these places but I've never seen a Waymo.
