D: It's a lonely road when you know what you want. That's a road where you won't make stops and pick people up.

A: Yeah, but it's even lonelier when you don't know what you want.

D: Right, but when you don't know what you want, you're more liable to pick up hitch hikers.

A: I know, and for the moment you feel like you're on top, but at the end of the day you still go home alone. Hitch hikers come and go, they're never permanent.

D: Right, hitch hikers are there waiting for the next car to stop for them. They wont get their own car because they have no drive.
