See I be riding just riding alone
With my daddy on my mind like you gotta be kidding
This line has several different possible meanings.
Wayne is around committing a crime (and he is doing so alone). In this context, his “daddy” would refer to his step-father, Rabbit (who he mentions in songs, such as Everything). Rabbit considered to be more of a father than his actual father was, so he looked up to him very much. In 1996, Rabbit was killed, and Wayne discusses that in this interview. Since Rabbit was killed (possibly because of gang related conflicts), Wayne is nervous for committing a crime/being involved in a gang conflict (especially doing this alone) because he saw what happened to Rabbit, and he doesn’t want to end up the same way.
Wayne is driving around and he is thinking about life. He and his real father (Dwayne Carter) are not close, at all, which Wayne discusses here. Since Wayne is just out and about, it upsets him to think about his father because he is angry with what he has done (such as leaving Wayne and his mom), and doesn’t like to think about it.
