Because they don't read the fine print which states in 1000pt font that your mileage may vary, and they just get upset when they drive worse in the real world than the car performs under idealized conditions. Its the whole squeaky wheel gets the grease syndrome, as well as people being whiny and selfish.
They want those numbers to reflect what they get when they lead foot it around.
Which was why the 2008+ numbers and testing was modified slightly to more accurately reflect real world by adding a few more tests, ones with more a/c usage as well as higher speeds which factors into the numbers to give a more accurate approximation, as opposed to the original rough approximation. However this just didn't give the people what they wanted, which was numbers lower than what they would actually see in the real world which would make them feel better.
There are many people which can beat or exceed the EPA numbers who don't complain that the numbers are too low, but those who bitch about not meeting the numbers say they are too high or are some how falsified.
