make your own bike lane

i found this via worldchanging

how cool would it be to have your own non-destructive bike lane? in oakland, bike lanes are few and far between, unless you count the awkward (often poorly paved and maintained) edge of the road between the lane line and the sidewalk. matt is great at riding his bike in traffic, but i still get a little anxious because of my knee injury a few years ago - the thought of getting stuck or in a position where i'm not able to move is frightening. having a light like this to help drivers not only see where i am, but also to alert them to how much room i need seems like a good step towards safe biking practices. it's a bummer these aren't in production yet - there are lots of negative comments on the initial site, with caveats for every situation (snowy streets, groups of riders, drunk drivers), but if these weren't made solely on the basis that there are certain situations that they couldn't be used in, would we ever have innovative products?
