Is it possible to rent a car without a credit card in Brussels?

Nowadays there are very strict rules about renting cars. Credit card is a must and must be issued to you as driver and not to anybody else.
The only option is if you can rent a car from a relative/friend.You may take bus/train to Amsterdam there are plenty and bus especially is very cheap.
Companies do not want to risk renting a car to you without a valid credit card. Lets take an example if you are caught speeding or wrong/failed to pay for parking how are they going to recuperate the money from you when you have returned the car and you are gone. Usually fines take more than a month to arrive so they need your credit card to charge for that and/or any damaged that you may have caused to the car or missing fuel level
