1: Airport rides are already available in Phoenix between 10PM and 6AM.
2: I have never seen a Waymo on the freeway without someone driving it (not monitored self-driving, but physically driving it). Take this with a grain of sand but it is my understanding that full self-driving on highways is still far away given the limited range of the (relatively) small sensors and the speed of travel required. That is: the sensors cannot see far enough ahead to react comfortably when going above N miles-per-hour. That might be a dated understanding of the issue though...
Source: I've been riding Weymo since 2019 when it first went public beta (NDA-restricted use). Rode one last night coming home from the airport!
