I’ve added a new concept to the notes section — the Robo Snow Plow. In the article I describe the value of plows that can patrol the roads frequently without need for staff. Since you don’t want to delay for recharging, these might be fuel-tank powered.
However, another interesting concept is offered, namely the repurposing of idle vehicles as temporary plows. The call would go out, and idle vehicles would travel to a depot where a plow or snowblower would be placed on them. Then they would go out and plow and clear light covers of snow. When done, or when needed shortly by their owner, they would return to a depot and drop off the plow unit.
Ordinary cars would be light and not able to plow heavy snow, but there are so many idle cars that you could get to all the streets before things got too heavy. If you didn’t, you would need to assign heavier vehicles and real plows to those areas. And everybody’s driveways would be kept clear by robot snow blowers too. Cars on the roads would give real-time reports of where snow is falling and how thick it’s getting. Cities might be able to clear all their streets, sidewalks and driveways without needing extra vehicles.
