Anyone know of a 100% reliable way to teleport someone while they're in a seat?

I would like to teleport someone without teleporting the seat as well.

I've looked all around and can't seem to find a method that is 100% safe unless I make my own custom seats.

When someone sits, use the sit function. Assuming there should be something like that. So when they sit just tp them, change the positions and to unsit them just go to their humanoid and uncheck sit. This method should work and will need to be scripted properly.
