Definitely I am finding it entertaining myself too but it's also fun spotting all the Initial D easter eggs/references.
I've never watched Initial D, I think I see the references you mention but some will pass me by, though I don't find understanding them necessary to enjoying MF Ghost.
There was a scene showing a drifting car that was presumably from Initial D, and I think references to the teacher (Fujiwara) are likely related to Initial D as well?
