I admit I did not go further than the title, because I assume the conclusion is in the title.

Waymo is considerably cheaper in LA (at least in a region) than Uber. I have no clue about Lyft. I know this for a fact, because someone I know has taken Waymos and Ubers between the two identical points, around the same time of day, multiple times, and Waymo has always been way cheaper, considerably so.
