Outliers are >60k miles already (less than 2.5 years into the wild) but you are certainly a minority north of 20k miles per year, average US driver is ~10k/year last I checked, as enthusiasts odds are we drive our cars more as weekend trips to pickup a gallon of milk somehow turn into 3 hour joyrides, "sorry honey, got turned around".
