Why do car rental companies prefer/require credit over debit cards?
A hotel can accept the debit card because each night they can withdraw the money. If you don't have sufficient funds they can instantly lock you out of your room. They an also limit your ability to access room service, and other extra expensive options. The rental car can't do that once you have the car. Plus they never know if you will bring the car back with damages, toll charges, and an empty tank of gas.
