When flying too fast especially on servers the vehicles will start popping in and out and then disappear.

It seems to happen when reaching any sort of unexplored chunk or just going too fast in general.

Ive noticed it is not a problem in multiplayer when no one is on but as soon as someone joins it impacts it a lot and will start happening again.

But asides from that, the issue in single player is pretty unnoticeable for the most part.

(Also I don't know if this is related to this specific issue but just incase all the crafting benches seem to also unload as soon as you leave the chunk).
