Suppressing that one part of the room heading

I refer to the “(in the vehicle)” that shows up when the player is in a vehicle. Is it possible to make that stop showing up?

Modify the “room description heading rule”. See thread: https://intfiction.org/t/non-furniture-posture-description-after-room-name/5578/1

Thanks very much. I swear I tried to find where this had already been answered.
