There are 6 billion, maybe 7 billion, people in the world. You can't lend all of them your car every time their car breaks down. Jesus lived in a different world -- a world in which a homeless teacher or rabbi could wander from town to town, on foot, be welcomed into the finest homes, given food, drink, and audience, and not have to be terribly concerned with the paperwork of life. Much as I admire the great teacher and try to honor the Gospels, we live in a world where if you don't have your OWN car, your OWN money, your OWN food and shelter, you get mowed down like an armadillo on a Louisiana freeway.
For the sake of your own survival, you have to take care of yourself first. Unless you are extremely wealthy, loaning your car out to all and sundry is above and beyond the call of duty. You have nothing to feel bad about. Loaning a car to your best friend in all the world, already you're a hero. Loaning your car to a co-worker? No effing way, Jose. She needs to rent a car or find some other way to take care of her own needs.
I learned through very bitter experience that if we spend all our time trying to help the helpless, we never have time to 1) help ourselves or 2) contribute to those who CAN be helped.
If I was in your shoes, I'd be happy to phone AAA for the co-worker. I'd be happy to give her the number of Enterprise Car Rentals. But she's on more drugs than Rush if she thinks she's borrowing my car.
The objectivist is just nutso. The gift is not diminished if you give freely. If you can afford financially and emotionally to give to people who are not so important to you, certainly, you are a wonderful person and a saint.
I just don't feel, in our society, that everyone should be required to be a saint. When you are without a car, this co-worker is not going to lend you hers -- and that, my friend, is guaranteed. We need not entertain objectivist nonsense to employ our simple common sense.
