Good point, but if you follow through to the source of the driving statistic that Derek quoted, they're actually using the median rather than the mean. Also, you've defined the "goodness" of drivers as a discrete measure. If you defined it as a continuous measure (say, a function of risky behavior and fuel consumption), then it is impossible by definition for more than 50% of drivers to be above average.
