Kobe later in an interview stated that video was fake and it was all "Hollywood".

And LeBron we all know was fake, Kevin Love did the real thing though which was awesome.
If they were both real I'd be more impressed with the LeBron video, that car is pretty low and plus I've seen bigger jumps over cars that were real.
