CamelTaxi

While you’re riding a camel, nearby villagers will hop on if there’s an open seat. When you dismount, they get off with you. No items, no menus, no interaction needed — just ride past them.

• Vanilla datapack (no mods)
• Minecraft Java 1.21.11
• Works in singleplayer and multiplayer
• Very lightweight, no gamerule changes
  
  PS: this is a datapack remake of the 1.21.4 version that did not work for me on the latest version of my singleplayer world!
