    Try not to extrapolate peoples' views, it's almost always incorrect to do so.
    Quite naturally, you missd the point.
    You can pick any number you want -- if the technology isnt there, it's meaningless.
    Tripling the average MPG of an 80,000lb truck - 5MPG to 15MPG - isn't possible any time soon -- the demands of service preclude it.

    So you know more than the companies that build the trucks? Because thats not what they said, as a cited earlier.

    The technology wasn't available at the time to meet the first go round of CAFE standards for cars, but we eventually met the standards didn't we? That is why the standards are phased in over many years. You underestimate the ability of technology to improve. We also may decide to transport more long distance freight by rail as it is more energy efficient. As we get closer and closer to peak oil over the next couple of years, increased fuel prices will make long distance freight by rail more cost competitive with trucks.

    How about going from 6 to 8?

    Because those are the numbers I saw.

    Entirely different set of circumstances and tech hurdles. Cars, for instance, were made smaller and lighter - truck weight remains constant.

    You underestimate the ability of technology to improve.
    You don't understand the situation.

    We also may decide to transport more long distance freight by rail as it is more energy efficient.
    As has been touched on before -- where it is more efficent/cost effective to transport freight on rail we already do.

    As we get closer and closer to peak oil over the next couple of years, increased fuel prices will make long distance freight by rail more cost competitive with trucks.
    As has been touched on before - long distance rail freight is already more effeicient and cheaper than trucks - people only move freight OTR on trips of ~1000 miles or more because of time constraints - something rail will never be able to match.

    I responded specifically to someone that wants to raise it BY 10MPG -- from 5 to 15.

    None of the companies that build commercial tractors have in any way supported the possibility of raising the average MPG by 10 to 15.

    You can’t haul 80,000 lbs. without using lots of energy; you bump up against laws of physics. Right now diesel provides that power and until there’s some new form of power you can tweak mileage up a bit with more efficient engines and aerodynamic truck design but as I said, you can’t defy laws of physics.

    How about we cut the max gross to 40k and then double the milage!
