Having a mobile bike lane following you around all the time might make you fell safe, but I doubt it actually makes you safer. If the light stripe to the left of the bicycle is not projected for some reason, might it actually degrade your safety?

Visibility is key. I,too, have seen ninja cyclists in dark clothing, no lights, on the wrong side of the street, running stop signs and red lights. One of them actually complained about my bright light as we passed in the morning darkness!
