Back in the 60s and 70s and80s, one of the universal truths about UFOs was that if one was nearby, car engines stopped running. It was such an ingrained truth, you can see an example in the very first X-Files episode in 1993.
Now, however, car stopping seems to have dropped out of the UFO liturgy. Even in stories from long ago. Last night with Knapp, for example, a caller told a story from 1976 in which a UFO flew directly over his car and trailed him while beaming messages into his brain. His car drove along until the driver pulled to the side of the road.
These changing “truths†are what make UFO stories difficult for me to believe.
