There already is. Its called a blinky. Nothing more needs to be added to existing blinkys so that drivers will ALWAYS recognize you as a bicycle. Besides, my best guess at the width of the lane that laser is marking is barely giving a cyclist 18" on either side. That's far short of the 36" on the left side that many cyclists need to feel safe. In America, a cyclist only needs clearance on the left, this device is the answer to a question no one asked.
