Switch track

The switch track could be crafted with an activator rail and observer and a redstone torch and what it would do is depending on which direction you're pressing with the movement controls that's the direction that the track will switch to if there's another track in that direction that it can connect to this could make building minecart tracks that are supposed to span across multiple areas like a train station of sorts easier to use but if it is a minecart without someone in it it will just head on the track that it was set to originally. Thank you for your time, listening to my idea, and making Minecraft better every day!
