So, I've had the unique privilege of having two different commutes that are about the same length. My current commute is a mix of light city driving and cruising at around 55mph. The previous commute was a mix of light city driving and cruising at around 80mph. Both commutes were between 25 and 30 miles each way.
- The average of 7 months of the 80mph commute: 31.88mpg
- The average of 13 months of the 55mph commute: 33.44mpg
