The "Green" community, the enviro people, are preoccupied with running all the cars differently. Our techno-grandiosity has us gibbering about high-speed rail - which we don't have the capital for anymore - but nobody is interested in repairing the existing rail system, which would be far less costly and hugely beneficial for us. In short, we are acting cluelessly. And life is tragic. The clueless usually suffer.
