Using "Pay now with Autoslash", I've just booked a Thrifty rental to pick up at HNL for a friend. The driver's credit card says that, in order to enjoy CDW coverage, "the rental agreement must be executed at the rental agency with your $bank Visa Infinite card".

How does Pay now with Autoslash work with Thrifty? Is the rental agreement "executed at the rental agency" or is it executed at Autoslash?
