i work in automotive. those things are nightmares for the environment. <br>plus they do not last very long yet and cost almost the price of a new vehicle. <br>the 500k idea is such a lie. they will likely go out in about 7 or years after production.<br>but 1st world production for any industry is just killing the world so ehhh. we gonna keep going til nothing is left.<br>all these companies saying they are going green are just shooting lip service and ppl buy it cause it makes them feel like they are doing something but no one wants to sacrifice our life style so we are gonna just keep it pushing.,(reply>), Oil is a bigger nightmare
