I think it’d be nice to quickly restart when grinding times solo on a track! Either a button to quickly do it anytime or at the very least something at the end of the race.
If I have a bad run going, it’s kind of annoying that I have to exit the game world and reopen it to try again. Even if I finish a run out I have to wait for the vote timer, wait for it to load again, wait for the ready timer (and remember to change the game mode every time on 150CC), and then wait for the track flyby.
It’d make “time trial” competition a lot easier to get into, I think.
