Minecraft wiki entry for Things_not_to_do, associated text: It is possible to ride a strider in the nether. You need a warped fungus on a stick to do so. However, if the stick runs out of durability midway in the lava, then the stick turns into a normal fishing rod, and the strider stops move where you want it to go and instead returns to its normal AI behavior, leaving you stuck in the middle of the lava ocean. You cannot dismount into the lava either without dying. So, it is a good idea to check your stick often.
