Virtual Plasma Crosswalks Will Protect Pedestrians

Stumbled across this, fascinating idea.

On congested city streets with many pedestrians, couriers and drivers, it is often difficult to cross. Many things are going on the same time, and even the best of drivers make an error here and there. The pedestrian has his/her own responsibility as well, looking and making sure they are out of harm’s way, but still…accidents happen and should be prevented.

The Virtual Wall is envisioned to reduce the amount of hits (pedestrians or vehicles). It is a wall created with plasma laser beams, which is to be placed on congested streets. . . .

I'm sure that'd be really expensive to implemented. I don't think its practical from an economical point of view.

will cost 10000000000000000000000000000

and will b in pakistan after 2300!!
