I made a poll to see if you guys want the rounds from speedkart to stay or not
I think you should rather have a GrandPrix system, where you race in 4 courses like this:
Blockhead 99999 completes Badspot Motorway from Example Cup, then he goes onto the next course of Example Cup, which is Blupo Valley or something. And so on until you complete the last course. Then you are shown in a Winner's room for some secs to see your glory or something.
