Driveway Friendly Snowplow

Ever shovel out your driveway only to have the snowplow come by again and fill it in with a foot or two of heavy, icy, chunky snow? Why not ask your ever-benevolent town to spend some of the big bundles of cash they never fail to collect every year to add a little feature to their big plows? Namely, a flat plate that flips down on the right end of the plow blade to briefly block the cascade of snow from going smack into your freshly-cleared driveway entrance. Come to a driveway, flip down the plate, carry that snow past said driveway, then flip up and the snow goes where the driveway isn't. Could even be triggered by a snowbank opening sensor. Call it a smart plow.
