If you want to get good fuel economy, sit ten feet behind a tractor trailer. You barely have to touch the gas. I just filled up my Toyota Camry and averaged 36 miles per gallon, after driving in tons of wind, and 1/3 of that tank city driving. I average 36, but if you net out the city stuff and the wind, and the fact that the drive had a net elevation climb of a few thousand feet, I was probably in the mid 40s. All hail gigantic trucks that get 2 miles per gallon that allow commoners like me to draft off of them.
P.S. I swear it’s safe. I mean, think about how long it takes a truck to brake. Even if you’re close to the truck, unless you fall asleep at the wheel you won’t crash into it when it starts to slow down.
