Well, I think if you do some more research you might change your mind. The video of people lined up at rental counters at airports in major cities was amazing. And they get to the front of the line, and yes, they have a reservation, but there are no cars.
The auto industry can't catch up with demand for cars let alone the fleet orders. Look at a Hertz Used Car websites and look at the mileage on the cars they are selling. They used to retire them before 30,000 miles, now it is about 90,000 miles because they can't get replacements.
