For some time, I wondered how the film was regarded so well despite the Bandit being a Boring Invincible Hero. Everything Buford throws at him is easily handled. Then it hit me. Buford is not the real villain. The real villain is Big Enos and his time limit. Buford is just a nuisance.
How did Bandit get personalized plates so quickly?
His contact in the Irish Republican Army set him up with personalized plates attached to a rotating series of fake social security numbers in exchange for a snow globe from Savannah, Georgia. Oh, wait... I guess that's WMG... he probably just had them and keeps switching them from car to car.
