Diecast cars are toys for young kids and childish adults, and as the matter of fact I do know of someone at the age of 28 and still collecting these silly toys. You may actually call Hot Wheels the king of diecast cars, and that’s because their marketing department always like to go the big way, like this really big flip-track.

Here’s a highway at Bogota, Colombia which got turned into quite a 3D racetrack by Hot Wheels. Going quite low-tech this time, but it surely isn’t low profile at all, Hot Wheels has placed a giant ‘loop’ in the middle of an overpass.

It’s certainly more eye-catching than a traditional billboard, and it still gets the message across that Hot Wheels are all about fun.
