6.5 whoop whoop!

I have a friend who complains that he has 5.5-6.0mpg average. He said he is driving atleast 70 all the time. I told him to slow down but he doesnt listen and says that the reason he drives so fast that he can enjoy passing everybody and he get more sleep time. I told him that my truck fuel mpg atleast 2mpg more and thats about $15000 savings every year on fuel comparing to his driving. So instead of listening to me that he needs to slow down, he just complaining and blames tires rolling resistance.
I told him that every 1mile above 55mpg loses 0.1mpg of fuel, but he still stubborn.
