See it like this. A = Pedestrians, B = Cars. A has no protection and no engine help to get forward. They have to go in deep snow that resists every step. Try walking on those 30 cm high gymnastics carpets that feathers the fall. It's like that. They won't stay on the unplowed bike roads. Bicycles can't travel in 10 cm snow. They will be on whatever surface have been cleared already. If that is the highway, that's where they will be. Category B on the other hand have a clear advantage. They have the engine and the antispin which makes them able to go through 15-30 cm snow without much problem as long as there aren't too many snow drifts, wet snow or packed areas. They are not allowed on the bicycle roads anyway and would not fit there. Besides, the main roads are taken care of a completely different entity so they already have their roads plowed anyway. They just have to get the first few hundred meters out on the main road and they are fine. Bonus if you have a buss road close by because they are priority -1, if anything is plowed, you can be certain it's the buss roads. Yes, I bicycle all year round but I also drive a car. Trust me, it's fair to do the walkways first, my car can handle the snow just fine most of the time. If not I'm not supposed to be out anyway. :-)
