Snow and ice

Gritters aren't doing the business by the looks of things. I have an idea which could solve all of the problems of snow and ice on the roads. How about a company develop a vehicle that has a major heater underneath it. Which would melt the snow and ice. The cost in fuel of generating heat would be negligible in comparison to the cost of lost business due to closed roads.

Water collected can be emptied at water-processing plants and we will not be stuck for tap water in summer.

Job done.
