It's the Re-routing SCP, it's a bus, but made up like a bug, the seemingly metal parts, is actually it's exoskeleton. It gets fake drivers by, when in a juvenile state, the parent will bring humans to the juveniles, which then swallow them, and the body is transported to the driver's seat, and connects the human with feeding tubes, and tubes to also hold it in place. They can even make the "driver" do common gestures by moving the tubes a bit.
