Help recreating the Tron lightcycle floor

Can someone explain how I might reproduce the floor in this image?



I know how to make a grid, and rotate it, and change the perspective, etc. What I can't figure out, is how to get the grid to blend together in the background as if it goes on for a very long distance. Even if I start with a huge grid and then rotate and shrink it down how I want it, it doesn't look like that picture. The 'far away' grid lines get faint and do not start meshing with each other.

Any tips?

If you have a dense enough grid, it will "blend" when you use the prespective command in Photoshop.
That pics seems produced by a 3d program, that's the best(fast) way to get a floor like that.
