From the LA times..
There were a few "truth or fiction?" moments when Bryant was shown on a viral-marketing video leaping over a speeding car, skillfully landing on his feet and hugging teammate Ronny Turiaf, who stood nearby.
After Bryant landed, he exclaimed, "That is how you jump over an Aston Martin, boy. That's how you do it."
The video was created by Nike to market its new Hyperdunk shoe and had drawn more than 300,000 viewers on YouTube.
The video drew concern from some Lakers fans, although Bryant wasn't really jumping over a moving car. He said it was created with special effects.
