Statistically Waymos are more expensive than Uber rides, but practically as an individual they are often cheaper than Uber, its very easy for the stated price to be lower
You might, but most people wouldn't, and more to the point, overwhelming more people will choose to drive their own car (or take transit) vs either Uber or Waymo.
If Waymo can drop its price by 50%, it could steal a lot of demand from normal cars and transit, but that doesn't seem like it's even on the conversation right now.
So its not even about willingness to pay more
