I had some good laughs on this Itasha video posted by youtuubeblows! Especially at the part where everybody starts dancing (@3:11) in their cosplay outfits and with the Evangalion itasha-van (or should that be dekoitasha?)! Not only does it show some Itasha to look at but also a serious otaku driftcar:
The Haruhi Racing Silvia S15 is a very beautiful one and apparently, judging by the screams by the Itasha girl, it can go sideways as well as any other drift car!
Now how long would it take before the Itasha catches on like this?
