I'm aware of CA splitting -- it's not been adopted yet elsewhere in the US. It's too bad that you had to experience someone who was "swerving in and out" and not the majority of riders who would split sensibly and safely.
Lane splitting is only supposed to occur below a certain speed; splitting above that number would be a violation, of course.
Take a look at Europe to see how easily splitting can be integrated, for both driver and rider. It absolutely does reduce congestion: bikes move smoothly to the front and away, freeing space.
American drivers just aren't educated to realize this because negative stereotypes about motorcycles are so prevalent in the US, and the many positive benefits of riding aren't presented as options here.
