Modern V/8's

Our current governing body is attempting to sneak through our legislative body new laws banning the new car industry from building SO CALLED inefficient internal combustion engines by the year 2050 at the very latest, and if they have their way it could be *** early as 2035. Simply because our current CHIEF in charge believes all the lies about automobiles being the main cause of global warming, when in truth it is one of the least causes. when compared to the global cattle market which produces TONS of uncaptured methane gas each year. And yes methane does harm our environment much more so than the carbon emissions from current vehicles. Has anyone compared fuel mileage of a vehicle running on e85 as compared to regular non alcohol fuels? Last i checked its almost a 20 percent loss in mileage, sounds to me like we use more gas that way. OH well, just my humble opinions.
