For example, the Nissan Leaf (like many other cars) has funny-shaped headlights to prevent excess cabin noise and drag from the side mirrors: http://www.nissanusa.com/buildyournissan/vehicle-images/2013...
Tesla's early promotional materials for the Model X show side cameras instead of mirrors (http://www.teslamotors.com/modelx ). But apparently they have given up on the regulations changing, because their newer design prototypes have side mirrors (http://green.autoblog.com/2013/01/14/tesla-model-x-makes-aut... )
