Not exactly about airline travel but I didn't see a good rental car thread

Yeah, rental cars are insanely expensive because rental car companies sold more than 1/3rd of their inventory last year to stay afloat.
What they don't mention in the article, of course, is that there are basically only 3 major rental car companies left even though it looks like airports have counters for like 10+ companies: Enterprise (National and Alamo), Hertz (Thrifty, Dollar), and Avis (Budget, Payless). It's basically one big oligopoly and the pandemic was a perfect time to squeeze the industry and they all did the same thing.
