Bob Falfa's backstory, has it ever been brought up/discussed?
I am curious if this was ever explored - I know Ford briefly reprises the role in the sequel film in which we find out that Falfa became a cop; I have always assumed that the disastrous drag race at the end of this film most likely served as a sign to Falfa it was time to grow up and move on to the next chapter in life (I mean, Falfa was like in his early 30s here while the rest of the characters were in their late teens and early twenties).
Perhaps the mystique of the character is what makes him so memorable (that along with the fact that he pretty much was the template for Han Solo)
