My biggest bugaboo is when people exclaim "This saved me 5 MPG!" Ok. Great. But what does that really mean in real numbers? Someone losing 10 MPG from 100 MPG to 90 MPG is increasing their fuel usage as someone else going from 10 to 9.89 MPG. 10.0 = 0.11? That is the MPG myth.
That MPG myth is one reason the EPA is adding gallons per 100 miles on new car stickers, since that actually shows a linear rate of fuel consumption.
