Triggers aren't used to drive in Mario Kart 8 though.It would have been cool if Nintendo had announced a new Plus Pro Controller (with triggers) just to play Mario Kart 8 with more precision when accelerating and stuff, but maybe they're holding it off to announce for Super Smash Bros. 4.
Other than this, I'm excited to try out MK8.
I don't even think any Mario Kart uses the triggers to drive.
