Advertising, that is.
(I know the answer - profit, greed, the wheels of commerce, the fuel that ultimately pays all our salaries, etc.)
This Hertz ad was sticking out of every seatback-pocket of the flight I took back in July. Hertz paid a lot of money to get that Mazda in your face (or in your lap, as it were).
They had the wrong customer with me. If I rent a car, it's the cheapest class available.
I must hand it to the advertisers - they are always coming up with new places to get advertising into our awareness.
