Turn signal backpack

The turn signal for cars was made standard equipment in the 1930s. Why is it that Memphis drivers can't seem to figure it out? Another thing Memphis drivers can't seem to figure out is bicyclists. Do I mow them down? Do I freak out and jam into the next lane to avoid them? Do I honk and make hand gestures indicating that I don't wish to share the road with anything that's got less than 4 wheels?

So designer Lee Myung Su has created a backpack that makes cyclists more visible to cars, and also avoids the use of those silly "turning" hand signals that no one knows how to interpret anymore.

I kinda really want one...
