Best use of lasers since star wars

If these can be seen during the day then count me in. Perfect for those narrow streets in Pittsburgh where it's too narrow to stripe permanent bike lanes (read: most streets in the burgh). Also, I think the city should have a free or at least highly-subsidized program to give these lights out to local cyclists. If they can't put in a lane, buy the laser lanes for the people.
They should invent a programmable version that you can put in your own message to shine on the pavement behind your bike.

I doubt most of the user-chosen messages would go far towards promoting harmony on the road. 
Sweet concept, though.
I think getting the city's public works department to employ thermoplastic paint for the line striping and symbols would be a more attainable solution to the current system of lanes. Although more expensive than the current paint they're using on Liberty Avenue, it lasts longer, a higher retroreflectivity rating and a raised relief finish (more grip for bikers, presence is felt through the steering wheel in passenger vehicles while driving).
I agree with sloaps, but Thermoplastic and Tape do better when laid down on fresh pavement. We have talked with DPW and they plan on doing this type of lane installation anytime a street is paved that qualifies for a bike lane or shared lane markings.
So what is the difference between this and normal lanes? What angle are they visable from? If it is steep how would it help a driver see/avoid a biker? Wouldn't a reflective tape like material be more advantagious, cost a whole lot less, and be much less prone to failure?
Hey, there's actually a prototype now.

Looks like daylight visibility is not yet even close. Bet it looks pretty spiffy in fog or heavy dust...
i would be willing to take one for the team and test this prototype... emails have been sent... the sacrifices i make for you guys...
if you happen to get another...
