The problem is that most people don't understand how cars work. All they understand is advertising.
When they buy a 47mpg hybrid and in the first week of ownership put their family and luggage in it with e10 fuel and go on a road trip at 75mph using the air conditioner and in-car entertainment they just expect to get 47mpg by default.
