JackBiggin and I messing around, this should be implemented some way / some how, it's a lot of fun. There could be something in a way you do /ride samsimx and then samsimx would have to accept in some way.
It's all for fun by the looks of it, and I like it for one It'd be an easier way to show your friends to outposts and such, hm?
you have a point there but wouldn't this be abusable in the wild? example: Player #1 OMG a scary creeper! /ride Player #2. Player #2 ??? Player #1 Theres a scary creeper help me plz! Player #2 ok fine. As you can see here player #1 used this to get out of death. Example #2: Player #1 I saw a huge ravine filled with ores but its like 10,000 blocks out. Player #2 cool but how i we going to get there cause i have to go soon. Player #1 simple u just ride me because i know were it is and flying is faster then walking! Player #2 /ride Player #1. As you can see here this feature can be used to transport this quickly and safely in the wild and this could hurt the economy.
And that's exactly why we should have it It looks like you're really over thinking it lol, this would just for fun and presumably only in town.
