Slipstreaming
This is a technique I only recently became aware of, entirely by accident. To
do it you must be behind another racer, and I mean literally behind. Not just
in position, but actually behind their cart. As you drive behind them using
your opponent as a wind shield some blue streaks will start to appear on
screen and you'll speed up a little. As you get closer and closer to your
opponent's back suddenly this weird blue wave will surround your kart and
you'll be given a surprisingly lengthy burst of speed that should allow you
not only to get ahead of your opponent, but a decent distance ahead too.
