Would it be possible to add a rail type that can be placed on the sides/bottom of blocks that unlock the rotation on minecarts and align riding entities' orientations to the cart so that they'll flip with them?
I've been looking for a basic vanilla+ roller-coaster alternative as most rail mods that can be used to build coasters are either outdated and/or incompatible with other minecart systems.
Bonus points if they're compatible with Create contraptions so that they can be used to make more aesthetic block coaster car contraptions, more dynamic moving platforms for Create obstacle courses, or just for Create factory stuff.
