Thin Privilege is not being trapped in the passenger seat of a car Reading this post reminded me of a funny Thin Privilege. Have you ever had a planet as a passenger in your car? If they fit in the seatbelt in the first place, if they lean forward at all and then lean back, they're stuck! Cars since some model year long ago include a child restraint system you use by fully extending the seatbelt to engage the ratchet and then release and it will not extend farther than that until it is unclicked and fully released back to the door. Every time it's happened I've chuckled to myself at their frustration. They only experience it as passengers because the driver's side in the front usually does not have this feature. Now you can trap a planet if you're into that! More info about the restraint system here. ALR – Automatic Locking Retractor: Allows belt to be pulled in one motion until fastened, then operates as a ratchet, winding in slack, preventing further extension (until completely rewound). In most belts, you will hear a faint clicking sound that indicates the belt is locked and ratcheting in.
