 Despite the fact there was no other information provided, people will automatically attribute that the accident was the driver's fault due to an internal factor (in this case, deciding to drive while drunk), and thus they would not allow it to happen to themselves.Another example of defensive attribution is optimism bias, in which people believe positive events happen to them more often than to others and that negative events happen to them less often than to others.Too much optimism leads people to ignore some warnings and precautions given to them.
