Recently the administrator of this website was contacted by Andrew Beck, Chief Spokesperson for the US Department of Energy. His inquiry was regarding a Hyundai that was attempting to post some seemingly fraudulent gas mileage records (presumably this would be you), and he was suspicious that this was a ploy by Hyundai Corporation to boost the market perception of Hyundai by reporting artificially high gas mileage.
We replied to Mr. Beck and informed him of the purpose of our site, and that most (all?) members here typically get 10-50% better mileage than EPA specifications, using a combination of aerodynamics, driving method, and engine modifications, and that this was not an implausible claim.
He then responded that he could not include this data set since it did not represent the "real world" expectations for a vehicle, using an average driver and real-world driving conditions with unmodified vehicles. We tried to persuade him that similar results are attainable by any other driver if they wanted to put forth the time and effort, hoping that the website would get some publicity. Unfortunately we didn't receive a response.
Because again, it would be misleading for the average driver. No doubt that he Hyundai Accent can be driven very efficiently. But without a way to tell show how you archived those numbers, the information is useless. Also I think they want to guard against people that are biased or misleading one way or another. Generally those results would be in the top and bottom 5% of responses. This is normal practice in a lot of statistical analysis.
