If we had a league table of the stupidest gadgets these would have to be very near the top, Indicatears, indicators for your ears.

Indicatears let’s you indicate to fellow pedestrians what your intended movements are, this minimizing those unfortunate often fatal 2mph collisions.

Ideal for busy shopping areas and crowded streets, the Indicatears fit behind the ears and are then activated via a belt/shirt clip attachment to signal your intention to turn left or right.

Absolutely bonkers but available to buy from Ministry of Gadgets.
