text: Most states have made it illegal to test computer driven cars because of their traffic laws. "Traffic laws are written with the assumption that the only safe care has a human driver in control at all times." That is clealy stated in the article. The dangers behind driverless cars are way more important than their actually purpose. No where in the article do they address the causes to the environment that the driverless will make. Will they be electric or powered by gasoline. More research needs to be concluded before Google and other companies decide to open these to the public.
