The title is a play on the phrase "rapid transit."
While relaxing in a steam bath, Bugs reads about the original fable and becomes incensed at the idea of a turtle outrunning a rabbit. Cecil, also in the steam bath, claims that he could outrun Bugs, prompting Bugs to challenge him to a race. This time, Bugs and Cecil agree to no cheating. Cecil, however, quickly reveals that his shell is now rocket propelled, allowing him to go a surprising combination between fast and slow. Bugs does his best to steal, dismantle, and destroy the device, but all to little effect. However, Bugs tops the turtle and crosses the finish line first. Nevertheless, it is Cecil who has the last laugh when he rooks the rabbit into confessing to "doing a hundred easy" in a thirty-miles-per-hour zone. Bugs is taken away by the police. Cecil says, "Ain't I a...um...stinker?"
- This was the final cartoon in the 1946-47 season.
- Cecil and Bugs had previously raced each other in 1941's "Tortoise Beats Hare" and 1943's "Tortoise Wins by a Hare". This cartoon was their final encounter. Unlike "Tortoise Wins by a Hare", this cartoon presumes that Bugs and Cecil have never met before now.
