Thanks for the compliments everyone.

The first picture was taken using a camera rig attached to the hood of the car... The car was going walking speed, and with the help of a long shutter, polarizer, dim lighting in the underground, etc. you get the effect. Then the camera rig was photoshoped out of the picture. Friend of mine designed the rig, and that was one of the test pictures I took with it to make sure it could support the weight of cameras (Nikon D3 with 17-35 2.8 lens).

Here's what one of the pictures looks like pre PS
