CES is big, loud and happens every year. For the past three or so years, the largest tradeshow in the United States has become a showcase for automobile manufacturers’ product rollouts…which is a far cry from the traditional car stereos and mega-huge flat-screen TVs you see walking the several football field-sized show floors.
