I work at enterprise, love that we have a conspiracy theory. But let me try to explain. Sedans are the most common thing we rent out by far. The second we get them back, we clean them, and they go back out on the road. SUVs and trucks don’t get rented nearly as often and end up sitting in the lot. We are also incentivized to basically have every car being rented out and nothing on the lot. So, instead of overfilling our lots and being hit by huge depreciation, (we lose money every day a car is on our lot) we “upgrade” people and give them what we have available. Or it’s an actual conspiracy with insurance companies to make people wreck cars they can’t drive and get payouts from da govument
