Let me just talk about that horn for a second, since you've brought it up. Even disregarding the fact that we've seen the course map and standings down there and the horn is an alternate view... what's so wrong with the horn? It's silly, it's fun. "Horn in the middle of your motion controlled wheel, like a real wheel, neat! Honk honk!" When they put it on there I bet they thought "he he how silly" and considered it a fun little thing to go along with the main actual game content of "steer your cart while looking at the TV." A very Nintendo-esque little bonus. Turning the motion-controlled gamepad a little bit more into an actual steering wheel. And this innocent little fucking thing has turned into a rallying cry for total shitcocks across the internet to mock the system for not being "properly utilized" or some crap.
When did we become so joyless? What's so wrong with a horn? Why are we analyzing every little stupid thing and determining whether or not it represents a proper exercising of system resources or blah blah blah? Just honk the fucking horn and smile, goddamn it!
