Using bits of the environment for creative ad campaigns is nothing new, but it is certainly entertaining--or can be. Case in point: this ad for Hot Wheels from Bogota, Colombia, which to onlookers like a vertical loop has been placed in the freeway.

A sign next to the loop, though not the first thing you'll notice when you look at the photo, confirms it's an ad for Hot Wheels. And why not? The latest from the company has even adults (playful ones, at least) looking forward to its release: the Video Racer, which films the craziest antics you can build for it, then plays it back on a tiny integrated screen.
