"Aufmerksamtkeitsteiler" is german for "attention divider" and dividing your attention is what you will have to do when watching this superamazing video.
The video is split into 4 screens, each showing a different perspective of the race: driver, TV camera, top down view, hood camera:

The racing is also quite close (not exactly clean though, sorry) so go clicki-di-click.

For the splitscreen effect I used avisynth & virtualdub, both freeware.
Yes, it is basically a FRAPsed replay x4 without editing but I hope you still enjoy watching it. I even pressed alt+f
