I was surprised that an Amsterdam auto rental required a passport, despite making the reservation through Expedia.com. I have no objection to requirement: I am left wondering:
What practical purpose (reason) does requiring the passport to rent the car serve?
The assumption is that there is a reason / purpose for said requirement.
Fortunately, the rental company was flexible and accepted my passport card issued by the state department (not a true passport, but a National ID card), because I left the passport in the hotel safe. I always expect to show my driver's license when renting a car.
BTW, This is not a requirement to rent a car in the Dutch Aruba territory.
