They do, but they buy or lease ordinary unmodified vehicles for a year or two then flip them at auction. Zero overhead here except for the buying/disposing of vehicles.
$80/day is probably a decent estimate, but once you include the optional insurance upsells and other add-ons (full tank of gas?) I bet they make way more than $80/day per car.
They also have very limited liability for what the driver does in their car while Waymo basically has unlimited liability.
I’m not sure what your piece of data has to do with how much Uber says you can rent a car for to drive for them. It seems like you want to really really believe that rental car prices advertised anywhere are complete fiction.
