good idea in theory, but (here in colorado at least) people will already know if it is slick out. because, you know, there tends to be snow in the air/on the ground. the salts/sand/trucks still need to be used to GIVE traction and clear the roads of the snow/ice. however, this system could be utilized in places that gets freezing rain.
