These cars already safer than human drivers and they are common on the streets around Google. So unless you mean "risk" as "risk of being slightly inconvenienced", neither of your points is accurate.

It is pretty clear that Waymo primarily intends to sell a taxi service, not cars directly. This taxi service would be cheaper and safer than any currently available so people of all incomes would benefit both directly and indirectly (fewer DUI drivers).
