Well BAR, I'm just figuring it out myself.  The first photo of the Ferrari is done with a background I found on the internet, and to make it look real, I had to make the car a relative size to the tire stack.  In the second photo, AI had been used to expand the background, which it did perfectly (IMHO)!  If you have a Photoshop membership, there are tutorials to show you how this is done, and it's fairly easy.
