This is an interesting picture since there's a form that's actually nice to stare with its many variations of brush size and discontinuities, all while not immediately giving out what it is until you get to read the title, so it's something you can only really see once!
The speed lines are really nice, the blue intrigues me since it gives me the impression the car has hit a water barrel or something and that's the only way I can think of to accentuate movement as you can only go so far with a still image and some deformation.
I'm just not sure if the shiny silhouette is a person or a seat, it looks like a pulled back seat to me. The convertible hood is massive, but I'm not sure if that adds to the picture. Certainly work on some more ambiguous stuff like this though, it's really interesting.
