Now that Japan has invented a car that runs purely with water, there would be no probelm of pollution, or petrol/gas charges anymore. Once that car steps into the market, i hope everthing goes fine and people should be using it successfuly with no major headaches. One good thing is that it can run even with ocean water and thats the vital point overall as the drinking water is limited and there are chances govt laying cost for water too(i know water bill exists but the one i specied might reach the petrol charges)
