If you really want to rent a car worldwide without risk even if you don't plan on returning the car in the end.
Just go buy a prepaid visa and load the amount of money of the rental period. Since most rental companys don't accept prepaid visas for car rentals, then take the t1+t2 off the prepaid card and put it onto a bank plastic. Encode and all that.
Of course you will need a good quality ID to match, but any USA Driver License will be good as ID along with the CC with matching name, which you will make.
This method is good if your not going to be returning the car.

Also this method will work in all countries, as long as the dump your using is a 101 prepaid card.
