This then implies that there IS something for them to test.

Having a simple metric for comparing different vehicles is key to consumers who cling to simple, intuitive statistics. The 230 MPGe tag on the Volt is simply confusing. But admittedly it is a very difficult task, as the NYT points out it is an inherently subjective procedure. There is no simple way to compare electrical energy and that stored in petrol.

So, I suggest an alternative that I admit is not perfect, but is simple and objective: Miles per Dollar. Measurement is trivial and homes in on the issue that is most important to consumers, especially in this climate. Take a look at my proposal. I welcome constructive criticism:
