25 10, 10:53pm
Either they do statistics or they single out all crashes wherepeople were wearing the seatbelt and survived and then send some shady guys to the past to prevent those people from wearing it, wait for the crash, check if the ones wo should be wearing it survived, then travel back to our timeline with the results and they make a tally. Whichever you think it fits.
