Thanking the bus driver in Fortnite became something of an in-joke for players for some time, until it was finally introduced as a fun little feature in 2018.
It's simple enough to do, but if you're wondering, this page explains how to thank the bus driver in Fortnite on all platforms, so you can be the polite and respectful citizen we know you all are.
Thankfully it's a simple one! To thank the bus driver, you just need to press whatever button brings up the Emotes wheel for you on your current platform - and, of course, you need to still be inside the battle bus.

When you've done it, you'll notice the name will appear in orange as opposed to red in that bottom left corner. Note that those above controls will be different if you've re-mapped the button for 'Emotes' at any point - either way, it's the same as the Emote button in-game!
