As the title says, what new modes would you like to see being added to the online mode?
Personally I'd love to see a so called Random Draw Speed Lap Elimination mode.
For Example, 8 people start in the tournament and get randomly drawn to face each other. They start about 5 seconds before the start line and have a boost to use before the start line and 1 after it.
You could have the option of a straight forward fight to the line, or doing it individually to try and set the 'purest' speed time.
Whoever sets the fastest time between the 2 progress to the semi's, and the other person is eliminated.
