What caused the accident?

The composition is actually kind of nice, although it doesn't really make much sense--there's no other car visible. What happened that caused the car to lose it's tire? There's no other vehicle, there's no barrier. Did it crash into it's own accident sign maybe? :P Speaking of which the sign is only posted one foot away from the car, it wouldn't give anyone warning soon enough. Finally a bunch of pyamids are kind of arbitrary...but style-wise, I really like how the rays of the sun kind of "swirl" in the sky, really makes it feel like it's hotter--even if I don't like the sun. And the image does a superb job of giving the sense that there's absolutely nothing to be seen for miles. I know you can't update this image any more since the project file was lost but just remember to think think more thoroughly about the concept when working on new pieces!
