"Although definitive research is scarce, Golf Digest surveys show that
the average golfer's driving distance increased from 193 to 205 yards
in the last decade"

The article is 6 years old but, if measured at that standard and adjusted slightly for the increase in technology I think the number would be right around 225.
It's all relative. You and I might hate playing at these distances because we're used to outdriving our playing partners on a consistent basis. My father on the other hand would say it's spot on.
I understand that we don't play video games to imitate "averageness", but you also need to consider that it's still BETA and we're a long way from the finished product. New clubs (with longer yardages) are on the horizon so, we just have to sit tight a little longer.
And so you have something to look forward to...
This is from their Facebook page. Yes, that is 285 on the TaylorMade driver yardage. I can't guarantee the picture's accuracy, but it's enough to speculate on. :D
