The Art of Racing in the Rain. Definitely more creative than A Dog's Life or Where the Racetrack Ends.
But what does it mean?
As with all things that require any form of skill, racing could be called an art. Racing in the rain is even more of an art: it's dangerous and should be left to the professionals, especially if you're driving a racecar that can go super fast and turn corners on a dime. If you've ever driven in the rain, you know that it's not as easy as it looks. You really need to have a feeling for how that car works, and how you can maneuver it in difficult conditions.
Racing in the rain is also, cleverly, a metaphor for life.
It's clear, if we pay attention to Denny's internal journey, that navigating through the rough patches life throws our way is also an art form. You have to learn to understand yourself, the conditions, the possibilities, even the small movements that could change everything. You have to be there, in the moment, always. Reaching the finish line with your racecar intact—either on the racetrack itself or, metaphorically, in life—requires some finesse.
