Here is a smart helmet with blind spot detection that keeps you out of trouble on the road. The Classon helmet not only alerts you with lights when cars are approaching in your blind spot, it also allows you to activate brake and turn signals with motion and gestures.
The cameras in the back scan your surroundings and let you know of cars with a light under the visor blinks. Users can activate turn signals with simple hand movements. The app for this helmet lets you change light intensity and gesture sensor sensitivity. The product is expected to ship in 2017.[where to get it]
