I am developing an automated vehicle that follows a course that riders can hop on and off anyt time they want.
Everything works great except when there are no avs sitting on it it has a very pronounces stuttering/jerking motion to it, then, when an AV sits on it, it's smooth as glass like every other vehicle.
Any idea of what causes this or how to stop it? Is it a known problem? The vehicle is a boat and is using the physics engine like all normal vehicles.
