i've struggled to get an uber for some early morning flights and can see it being easier to waymo to millbrae bart and connect to SFO than waiting a long time or paying insane surge prices for uber
You could also waymo to millbrae and uber to SFO. The price ($5.20) for BART to SFO makes it unattractive, especially since you often have to wait for a while. I've caltrained to millbrae and taken uber to SFO for $12, which is often worth the time tradeoff for me.
