If a wave of the hand or a middle finger aren't enough to convey your thoughts to other drivers, you might be interested in the Drive-e-mocion. This electronic display adheres to your back window and communicates such messages as "Thank You" and "Back Off," as well as smiley and frowning faces. Unfortunately, those are the only four messages, leaving nothing really appropriate for when an errant driver drifts dangerously close to your driver-side door or that Sunday motorist merges on to the freeway in front of you at a cool 25 mph. Sometimes technology just can't replace good, old-fashioned sign language.
