Task: Question Answering
Input (English): Context: After finally making it across the bridge , the cab spins off the road and straight into a tree . Usually , the AI controlled drivers of Liberty City will withstand any sort of vehicular battering you throw at them , and immediately drive away when the opportunity arrives . So when this taxi cab did n't move after smacking head on into a tree , I checked to see what was up . The driver was dead . His forehead , smashed on the steering wheel of his car , caused a constant whining of the cab 's horn that I did n't even notice at first . Then it happened . Something I do n't think I ' ve ever felt while playing a video game , and definitely something you should n't feel when playing any of the GTA games . 
Question: What may be a reason for the car accident ?
Output (English): The AI in the video game had messed up .
