Air travel and shipping are more than a "rounding error".

Admittedly this data is a little old (20 years), but today's numbers probably aren't that different. It shows, out of US petroleum production, that only 47% is used for gasoline. 8% is used for jet fuel, 22% for diesel and heating oil, 5% for coke, 3% for asphalt, etc. 53% is not a "rounding error".
