During Zasa's final stroll, Vincent boldly and recklessly disrupts the entire procession to publicly accomplish his goal.

I remember thinking that this was done purposely to show the contrast between a young, deliberate Vito and a young, rash Vincent...and possibly to show Vincent's similar temperament to Sonny.
