I used 2.5 seconds. It is dark, the driver is tired and can not predict the behavior of the drunk pedestrian, and in times like now it might also be snow/ice. Road safety is part worst case scenarios and part about mitigation. It is why drivers here are trained that children will at any point run out on the road during play without them thinking. Children behavior are more unpredictable compared to adults and so it is the drivers responsibility to be vigilant against what they can't foresee.
