Greatest bicycle accessory ever invented?

Well they sure beat those little reflective placards. Behold the "LightLane". Indeed I will probably be retired or dead by the time Anchorage has the same amount of bicycle lanes as Den Haag in the Netherlands, but as you can see, the LightLane is your own personal bicycle lane that will go wherever you go despite the city you live in being absent of such lanes. Unfortunently of course, riding during daylight in a city empty of bike lanes will remain another story. BTW the LightLane was thought up by Altitude Inc.. As of now, there is no actual prototype in existance so far. Somebody better develop this thing fast though!
