what is a courtesy car?

[olasek]

Courtesy car.
Advertised often at small airports. (First come first serve, etc)
How exactly does it work, what are the fees?

Having never needed it, I did not realize (until now) that you have to fill out and sign an agreement to use it:

I have no idea if their agreement is normal or an anomaly.
