What new things should Nintendo add in Mariokart 9 (Next Mariokart)

Here's another one I thought up when I saw the colour variations of Shy Guys and Yoshis, but forgot to add earlier:
Why not colour variations of Toads? They come in your bog standard red, which we already have, but also have purple, blue, yellow, green, and I don't know but there may be others. I think the colour variations of Toad should be introduced- And maybe whack Captain Toad under that group?

First person driving, Mario Kart 3DS had it, 8 should have had it too.
 
Team Vs Race and Battle should have options for 3 and 4 teams, with the team colors being green and yellow. Fake Item Boxes should be colored to match those.
 
I want first person driving too, and give your characters viewmodel arms too.
 
It wasn't in Mario Kart 7 though.
 
In the settings menu in the Mario Kart Channel, you can change it.
