Functional winter mudguards

Here's an idea for an automotive company, or perhaps even a parts supplier like Magna :

Build mudguards that are smooth on both sides - including the side that faces the tire! This way, during the snow-filled winter months here in Canada, snow has a hard time sticking to it.

If you've ever driven in snow, you'll notice that occasionally during heavy sticky snowfalls you might notice some degradation in turning, or braking ability, or even strange noises.

When your tires travel across the snow some of it is picked up in the rotation of the tire. Most cars have a slippery smooth surface on the underbody of the wheel well. The snow will travel along this path until it hits the mudguard.

Being the rough-edged, bumpy, and cavernous moulded plastic it is, the snow will undoubtedly stay there gradually building up like a rolling snowball.

My idea? Round it out to continue the flow of the smooth-surfaced wheel well ... that way the snow has nowhere to stick and continues on back to the road.

Granted in an industry where every penny is pinched (which reminds me of a story an automotive engineer told me when I asked why all car underbody parts weren't painted ... to save a few extra dollars) I can see how this "might" be a valid excuse, but if today's generic household product can be packaged in virtually indestructible plastic packaging, I don't see why it would cost THAT much more.
