So not a statistical question. In general, will I use less gas driving at 55 miles an hour than 70 miles per hour? So this feels statistical because it probably depends on the circumstance. It might depend on the car. Or even for a given car, when you drive at 55 miles per hour, there's some variation in your gas mileage. It might be how recent an oil change happened, what the wind conditions are like, what the road conditions are like, I mean, exactly how you're driving the car. Are you turning?
