Depends on the area. I grew up in a bad neighborhood and everyone was grifting. If you gave a random stranger a ride you would get to take a tour of the roughest places in your city and maybe a "friend" that sees you as a free taxi driver. It was rarely malicious, mostly just people were poor and didn't have access to transportation. But their friends and family can sometimes be pretty dang nasty.

This is called being a "Soft Touch."
