There are technically thirteen levels and three different battle modes to play on, giving you the chance to win out of 36 different matches. Given you have to win each map at least once on every battle mode to acquire the meta trophies for each mode, this should be the first step and the easiest. You can play the entire game on Easy mode, which makes some drivers waste some time driving into the same spot, while others will mess with one another until you get close.
