It's worth remembering that although averages are useful, there are no actual average-in-all-respects households. Also, the tail of the distribution is likely influenced by some very-high-mileage outliers.

If we do the same stats with the fitted distribution (which avoids some strange outlier noise at the end of the empirical data) we get:

• 13.8089% of trips are less than 1 miles
• 29.1367% of trips are less than 2 miles
• 40.7579% of trips are less than 3 miles
