I considered getting a Waymo once in LA but I found that since it doesn't go on highways, it is incredibly slow, and cost $60 to spend the same 1 hour as riding the E line for my trip. I ended up riding the E line.
Just last week, I was able to walk to the E-line in daylight; E-line to downtown; E-line back; and take Waymo at night home. It can be useful for a "last mile" scenario.
Yeah the human drivers in socal are really choosy at night. Many a times I’ve waited 20 minutes for a ride because I was not in a choice neighborhood to deadhead rides I guess.
