was a feature built into a temporally duplicated DeLorean time machine
by Emmett Brown
. He programmed the car to automatically jump to four-dimensional coordinates
if he did not return to the vehicle within an alloted time. As this had happened on one of Doc's journeys through time, the DeLorean went into this mode, entered temporal displacement
, and appeared outside of his garage
on May 14
for Marty McFly
to find. Marty looked for Doc in the vehicle, but only found Einstein
, a shoe, and a tape recorder
in the car, which instructed him of Doc's calamity.
When this feature is used, it also leaves the "Last Time Departed" blank, implying that it bypasses that part of the time circuits when this feature is activated.
It is unknown what would happen if this were activated more than once, as it would materialize in the exact same time and place as any other instances of itself that had done so.
