@ LCC, yeah yeah, of course, but that's not the point. In my scenario you only have the two options. But yes, I know, you have to say that. And yes, I was being just a wee bit flippant.
@ Whiskey Mick, I, too, ride both bipedal and motorized cycle, and I tend to agree with you. While filtering (aka lane sharing) is, rather surprisingly, allowed and encouraged here, that's not quite the same as allowing motorcycles and scooters to wholesale use the dedicated bicycle lane. Quick side note; bicycle lane does not equal bus lane (where there's much more room).
In California, where I cut my teeth, lane sharing is tolerated if done reasonably (it is NOT legal, as is commonly believed), but even there, you NEVER motorcycle up the curb-side. That *will* get you ticketed pronto.
I'm prepared to share the bicycle lane with motorized two-wheelers when traffic is stopped, and at bicycle speeds, but that's about it.
