The answer to the question is no. I rode a motorbike in the 1970s in London, where lane filtering was widely accepted, lane splitting not so much. In those days most cars were so much slower than bikes that us motorbikers almost considered them stationary objects, even when they were moving. It's a bit different now, with almost all cars powerful enough to accelerate quickly in city traffic. Allowing lane filtering and splitting now would enrage a lot of car drivers, who would rightly see it as butting in and driving dangerously.
