I admit - I bit a tad too hard. Sorry!
Lack of visual cues at night, especially peripheral, can be a player. Sometimes the crew may be distracted, heads down, feet on brakes (but not hard enough), and the aircraft may gr-ad-ual-ly move off, without any noticeable acceleration.
Ironically, ATC switching off all the other lights can contribute to this example.
Physiological effects, fatigue, presumption, CRM breakdowns, are but a few of the reasons for such a simple mistake.
