Was driving the vehicle at a fairly lower speed. (35 mph). was utilizing the cruise control, moved my right leg, and due to the positioning of the ignition, my leg bumped the keys slightly, which caused the key to turn into the position where the vehicle was no longer running. upon noticing that the engine had stopped running, was still successfully able to place the car into neutral and restart the vehicle without causing an accident- however, had i been driving at a higher rate of speed, this could have been catastrophic.
