She's a little hard to see in the video, but modder AJLethal of Costa Rica has placed a modified version of the Krystal Trophy model from Super Smash Bros Brawl in about a dozen of his Need for Speed car mods. He currently has the most mods on the entire site, so Krystal is getting some exposure through this she might not otherwise have.
You know, this is not what comes to mind when you think of Krystal game mods, but this is actually really clever. It's a subtle nod to the blue vixen that can be added everywhere without spending too much time handling weird edge cases with model rigging and Krystal not looking right in some parts of the game. As the driver, she always works.
Here are all the Krystal mods I found. They can all be downloaded from these pages.
