My point was that when the median of something is much lower than the average, the "average" member of the group can be way below the group average for that thing.
Consider a group of 200 people, where 50 drive 10 miles a day, 100 drive 20, 20 drive 30, 5 drive 40, 5 drive 60, 5 drive 80, 5 drive 100, 4 drive 200, 4 driver 400 and 2 drive 600.
That's 8100 miles per day by 200 people, giving an average daily drive of 40.5 miles. If we assume 40 miles is too much for an overnight charge on an ordinary outlet to cover then we might think this means the average person would find they need more than an ordinary outlet.
But 75% of those people drive 20 miles or less per day, and 85% of them drive 30 miles or less per day.
In standard usage, "the average member of the group" simply refers to the hypothetical member whose relevant attributes are those of the group's average.
