Most of the time they are just profitting from "the guy with the car".
I remember once doing the free taxi cuck for a roastie that would be a skincel if a boy. I tried to make a conversation. The only words she knew might have been "yes" or "no", because she literaly didn't say anything but "yes" or "no". Afterwards, however, she made fun of me in my back because I actually offered her the ride (yeah, I was really a beta cuck by the time) and she thought I did this because I was trying to hit her or something. I did this because we were going to the same lecture and she would have been late if I had not been there. Beta cuck at its best.
I had maybe 3 or 4 really friendly ride involving a girl. But nothing that ended in a relationship, my car isn't appealing in terms of status.
