BMW Smartglasses are basically a HUD for riding motorcycles

"Once you set them up, the glasses essentially function as a head-up display for riding. There’s a projector built into the right-eye frame that puts essential information directly in your field of vision. Vitals like speed, the posted speed limit, gear and navigation directions can all be selected and projected from the glasses. You can also change the color of the projection to your suiting."
