When I first tried drag racing in the mid 80's (at Capitol Raceway), they were still using the method OMT mentioned to measure 1/4 mile MPH. They had cones in the center of the track where the lights/reflectors were located (not the orange styrofoam boxes like today). You always stayed in the throttle until you passed the 3rd cone on the top end of the track to get an accurate MPH reading. It's probable that this is where the term "driving it out the back door" came from.
