His Rolls-Royce became an omnibus, bearing parties to and from the city between nine in the morning and long past midnight, while his station wagon scampered like a brisk yellow bug to meet all trains.
Fitzgerald uses another insect simile here to show how fast Gatsby’s station wagon, which isn’t so nice of a car, was to leave when he had parties. His Rolls-Royce became a bus for transportation on the weekends demonstrating his flashiness and “new wealth” at his house. The station wagon can also be compared to the people who attend Gatsby’s parties because many of them end up leaving after a short period of time.
