While one has to give credit to Honda and Toyota for producing hybrids, I'm sure they (Honda and Toyota) don't have a problem with posting EPA ratings of mileage estimates. They get to charge a premium for cars that don't meet mileage expectations and are not much better than non-hybrid economy vehicles in regards to MPG. Furthermore, everyone loves them for making an evironmentally responsible vehicle. On top of that, they are legally protected because they are required to post EPA rated mileage estimates.

Now, imagine if GM made a hybrid that got lower than expected mileage. I'm sure the press and special interest groups would be all over them for falsely advertising their vehicles. But, unfortunately, GM hasn't even stepped into the ring yet (with the exception of the mild-hybrid trucks).
