This actually might work and has a certain aesthetic that appeal to certain demographics. Would look great on a VW bug for example. From the article itself this is what it has to say.

>No matter how many cameras or sensors they use, autonomous cars will never be perfect, but research coming out of Japan suggests that a simple upgrade could help reduce the risk of self-driving cars hitting undetected pedestrians: a pair of animated googly eyes that make it obvious what the vehicle has or hasn’t spotted.

one issue I can see is that if the eyes malfunction and someone gets hit then that can lead to a lawsuit. Innovative though.
