I live in Montreal. Here bikes, skateboarders, scooters with no licence can do lane splitting or filtering while their "drivers" don't even need a driving licence/know rules of driving. Why motorcycles could not have the same rights while they generally not only have a motorbike, but also a car licence? It would also make car drivers more careful with bikes and skates as they would probably look more properly in their mirrors. Less pollution, less time in the traffic, I don't see the point of not experimenting it. If car drivers don't understand it at the beginning, it will make them more sensitive to 2 wheels drivers in the end, motorbikes or bicycles.
