First of all, you are posting this in the wrong forum. It should be in the photo gallery forums and not the Aftermarket Modification Forums.
I can do that too.....
The first two, aren't photoshopped, but the last one is photoshopped ....
The first two, we had one of the members and poster on these forums (Team haymaker) hang out from his Soul while his buddy was driving it, and take rolling photos of the group of Souls as they were going by...
You see, in REAL Rolling photos, the background isn't in a Motion Blur most of the time except direct shots against the background.
Mostly, it's Photoshop creations that have the Blurred background to make it appear as the car is moving fast.
Here's my example:
the original image:
(My Soul is perfectly standing still)
And with the Photoshop filters, it is now moving 150 kms/hr

It makes a very nice and almost convincing effect.
