The only way to do that exact photo is to use a a boom attatched to a suction cup placed on the body of the car you're shooting. You can actually tell where it was photoshopped out above the headlight. It was attatched to the hood.
The other way to get the look of rolling shots is to do a "panning shot", to do this you usually need a lens with special panning image stabilization which is only found on high end pro lenses. This is relatively easy to do, shutter speeds are going to be around 1/4 of a second.
If you don't have panning image stabilization you can still get a decent result, you just have to do many repeated tries and be very good. It will take you maybe 10 shots to get a sharp one. Shutter speeds will be around 1/15th.
If you think you can just follow the car you are trying to get a rolling shot of and put the camera out the window I would forget about it, this has a very low success rate and leads to lots of blurry shots even with really good drivers, and lots of practice between both drivers and the camera person. Shutter speeds will be around 1/8th.
Here are a few examples of a panning shot I did without image stabilization just for practice:
You won't get much blur but it will still look cool.
Hope that helps.
