Remove the dpf law and strict diesel emission laws

There is proof that these "dpf" diesel particulate filters in diesel trucks today actually pollute worse then a diesel with out, in theary these trucks equiped with this filter are getting roughly 8mpg or less as compared to a deleted emmisions truck are getting 23+ mpg do the math thats 15 miles more on the same amount of fuel there is proof that diesel particles are to heavy and fall after 200 feet, to ban this law would help the economy greatly for instance that cup of coffee your drinking or that conputer screen your looking at, 99.9% of everything you own was shipped by diesel at one point in its life i feel we should be focusing on getting these motors to get better mpg not make it worse
