I have written about this before in similar discussions. I think men just cannot comprehend how much women are willing to pay to guarantee that they can avoid a scary situation in a car with a stranger driver. Ask any woman: Have you ever had a scary experince in a car with a stranger driver? Probably 100% will say yes. I would say Waymo's primary customer will be middle to high income women in urban environments.
Also middle/high income parents. Shuttling kids to and from school and activities is the real killer use case for driverless cars. They're actively working on getting this legalized.
