Snow, Parked Cars and a Creative Solution

Is this a viable solution? When there is heavy snow, in a country that is not prepared for it, roads become unpassable and traffic flow is impeded. As a result, people stay at home, or abandon cars, restricting the width of the road. This further impedes traffic flow. As a result, snow ploughs either cannot gain access to the road (Prevented), or can only clear the center of the road of snow (Counteracted). There is a physical contradiction at the heart of this situation. Cars will be parked in the road. The road clears to be clear of cars to clear it of snow. Both cannot be true at the same time. What is the solution? How about this? Separate in Time. Park on one side of the road on Monday, Wednesday and Friday and the other side of the road on Tuesday and Thursday. The snow plough could then clear both sides of the roads by the end of the week.
