Even motorcycles are getting in on the rear view camera act. Go to this site to browse cameras that might suit your requirements. The article below illustrates a camera in the helmet of a motorcycle driver that shows what is in the rear of the cycle.
” According to Skully’s press materials, the display is not in the rider’s primary field of vision, and appears as if it were floating 6 meters ahead.
|A heads-up display shows the rider turn-by-turn directions or the image
from a rear-view camera.
The heads-up display can also show the image from an integrated rear-view camera. Skully notes that this camera has a 180 degree field of vision, so the rider can also see when it is safe to change lanes.” http://unbonmotgroundswell.blogspot.com/2013/10/gps-rear-view-camera-in-motorcycle.html
There is good reason to doubt that even bicycle riders will get into this act in the future. What is behind us when motoring is coming into full view without turning around or looking into a mirror that only gives us a partial display. Rear view camera technology promises to improve safety in many aspects of our lives.
