Snowploughs: I'm pretty sure the snowploughs used in Poland, where they can be sure of getting regular use for at least three and usually four months a year, are not dedicated, single-purpose vehicles. They're just small trucks loaded with grit, a spreading attachment on the back and a blade (with rubber bottom) fitted on the front bumper. And it still leaves the problem of what to do with all the piled up snow. It also doesn't get rid of ice.
