Mario Kart 8 Deluxe: 12 Tips & Tricks The Game Doesn't Tell You

2. You Can Honk Your Horn & Call For Help In Renegade Roundup

Cheers to loloweb for this one, as it highlights a couple of additional in-game features. The first only serves to annoy other players when you speed past, but hitting L when you don't have any item will honk your horn - something that differs for each character.

Second, do this when imprisoned in the Renegade Roundup mode (MK8's version of cops n' robbers, where the 'criminal' Renegades get put in cells) and you'll cause a 'HELP!' prompt to appear on your companions' HUDs.

If you're playing Renegades, winning the mode is contingent on freeing your companions as frequently as possible, so if you find yourself on the receiving end of a Piranha Plant's bite, start wailing on your horn until you're set free.
