- —Marty McFly
The digital speedometer in the DeLorean time machine was used in synchronization with its analog counterpart to determine the speed of the car as it accelerated to reach temporal displacement. The speedometer is set to 88 mph and will not go over the set speed.
While escaping 1885, Marty McFly referred to the digital speedometer as the locomotive pushing the DeLorean got increasingly faster, screaming out the speed over one of the walkie talkies as Dr. Emmett Brown got closer.
