It will never be fully predictable: people make mistakes. It is always safer and better to assume that someone will do something unpredictable like run a red light. It could even be because of mechanical error.
When riding motorcycles in ~~Asia~~ some asian countries (did it for 6 years), you assume that people will run the red light. It happens, during rush hour, 100% of the time.
So, you drive appropriately and it is safer because of that.
Edit: changed Asia to some asian countries. I didn't want to be specific but ended up being to general which was wrong.
