Hybrid mileage claims are hype?

    I thought I was cynical but I would not have guessed that the EPA
    doesn't
    measure how much gas is used in order to figure out how much gas is
    used.

    The 19-year-old EPA tests for city and highway mileage actually gauge
    vehicle emissions and use that data to derive an estimated
    fuel-efficiency
    rating. The EPA tests pre-production vehicles in a lab to simulate
    vehicle
    starts and stops on crowded city streets and open road conditions.
    According to the EPA website, "The tests measure the waste substances
    emitted from consuming the fuel, not the actual fuel consumed. From the
    measurement of emissions, EPA can estimate the miles per gallon achieved
    by
    the vehicle on average."
