Why is it that some 75+ mph drivers claim to get better fuel economy such as 38 to 40 mpg compared to others who really try to get the great mileage and don't get better than 30 mpg?
Other than variations in driving skills, I am beginning to take the bragging statements of faster drivers with a grain of salt.
