Full disclosure, I'm an American, and one thing we've done very well is made it super easy to rent cars. You arrive, go to the lot and pick out your car, and drive off. They take care of the transaction when you go to get out of the garage. Returning the car is just a drop-off. No interaction is even required. As far as getting to the car, I use the airport's car rental. In the States there are HUGE rental car inventory at the airports. I either have someone ride with me to go out and get the car, so I can drive the rental back and they can drive my car back, or I just uber out to the airport. For reference, I live 30 minutes away from the airport.
