All of which means we need nearly as much parking in the future. Sure we save a little because the car will leave your immediate area (read CO2 and other emissions) for free parking out of sight, but they are still parked. You will want it parked somewhat close to you because you never know when you will have a family emergency and have to leave early.
Or at the very least, the price would go up a lot. Who cares about the cost, when the value of the sold good is so high? Why sell it cheap? I note that Waymo has no intention of selling the things.
But I don't think there is any manufacturers that rent vehicles for short term and neither there are any rental firms that manufacture their cars...
In the end making things and renting them is different businesses.
Unfortunately most cities in the USA have parking minimums so even if a market change occurs and they are all empty the lots will stick around for a while until they are no longer legally required.
