Wikipedia did not mention a big drawback with these roads, though: If there is an accident, a vehicle breaks down, or a truck gets stuck in snow (this is Sweden, after all), there is no way for emergency personnel to get to the scene except by going the opposite way. And there is absolutely no way for traffic to get around an obstacle until the center cables are removed.
