Ok so lets add this up. If its worse for cars we will probably end up paying more to fix our cars, because of the damage it will cause. It in the long run is only polluting the environment even more by releasing more CO2 gas which is going to be funny as hell when you think about it. Once the environment gets so F'd up that it starts to create heat waves that end up destroying farmers crops so they cant produce corn. Which in turn makes it so we cant produce fuel, and then in the end will F up the economy more and make us go straight back to relying on fossil fuels. If ethanol is used 100% in cars there will be 2 things that will happen that i am very interested in. 1. Fuel prices will go up because we have more effort in producing it and we must pay for the fossil fuel to make it on top of what ethanol cost to make (most likely). 2. Fuel prices will go down which will show that we have been paying more for fuel then it actually really cost and only have been filling up the big wigs pocket books.
This all should be very interesting to see if people start to wake up and realize we need to stay the F out of Environmental issues because all we end up doing it messing things up more.
Anyways i digress and am done with my rant. Have a good day and dont forget Fourmula 1 in about 9 hours.
