Again, people need to understand the the underlying issues, become informed and vote for politicians/policies accordingly. Most people are sold on the "saving something for our children and grandchildren" mentality. But no one is telling them what the true reality of that is. Believe me, I am all for saving the planet, recycling and such. But we are headed down the wrong path currently and this discussion has shown some of the flaws with the logic. For the most part, most people won't do anything until they are forced too, and by then it's too late to do anything but follow along.
Sorry, but I think we have gotten away from how this relates to GM's decision from the original post. I think manufacturers are saying what is expected of them now, and will let the chips fall as they may when the 2030's get here.
