My first Speed Racer movie fic! It's a oneshot/drabble. Review?

The need for speed.

He always been interested in racing. He loved the smell of the track, the wind in his face and knowing that this was something that could bring a whole stadium of people into silence...while they waited for somebody to fly past the finish and win the race!

But winning and driving aside, there was one reason he raced. The reason he never stopped, or gave up, or quit believing in himself.

His brother. Rex. Rex had taught him everything. How to scope out your competitors, how to fix every inch of the race car, and how to feel the car and it's every need.

Rex was the reason that when sweat trickled down his forehead, and the car crashed this way and that, he never even considered for a moment to stop. He did it for Rex.
