Luck can be defined as the positive or negative result of an unlikely event. If you perform an unsafe action on the road such as driving at inappropriate and excessive speed, under the influence of alcohol, medicinal or recreational drugs or driving while having fatigue, travelling in darkness or in situations with inadequate visibility because of environmental factors (rain, snow, fog) or while vehicle related factors (braking, mechanical issues) or if there are defects in the road design, layout and maintenance all of that could cause an accident but if it does not happen, there is a positive result to the event and therefore you should consider yourself lucky.
