Very enjoyable reading. I didn't play any Initial D when I was in Japan last year, although I like the TV-series. But I'll get more chances since I'm moving there soon.
To me, it looks like there's no grip at all - the cars seem to drift real easy. I don't have a drivers license, but do you maneuver the car at the same way on a real car as in IDAS 4 (when drifting)? And what happens in the second clip? Does he lose control of the car or did he get so far ahead (110m?) that he won the race? Something I noticed in the third clip is that the wheels of the opponent doesn't seem to turn (at least not as much as they should when drifting). But then again, this game doesn't seem to focus on graphics, and it still looks really good on those videos.
