This is quite an interesting concept - a device that projects a bike lane behind you when you cycle.
Wonder if the police will see the humor in this if I were to road hog…
I wouldn’t mind seeing something like that here in Sydney, except i would prefer to be fluorescent /glow in the dark green light more. 
:brilliant idea , i wonder does it come with 1 wheel
I’d get it just for a laugh.
For it to work it’d have to have some stabilizer to keep the image steady on the ground despite the motion of whatever the projector is attached to. I doubt this is market-ready yet.
That’s really neat. Our town might get a bike lane though.
thats awesome!!!
get one witha unicycle on it, :D. that’d be cool
