The mean is given by the number I posted, about 1 death per 100 million miles traveled. That number includes drunk drivers, distracted drivers trying to text, everything.
The point is that "1 death per 100 million miles traveled" is the mean average, but most drivers do better than the mean. Mean, median, and mode are not the same and the mean crash rate is not relevant to most drivers.
It is. The mean is dragged down by alcoholics who drive drunk every single day. If you never drive drunk, that gives you a significant advantage.
