Lane splitting or as we call it here, filtering, is perfectly legal here in the UK. It is also absolutely fine in a lot of european countries.
I personally find it incredulous that it is not allowed in some countries. I don't own a motorcycle to sit in traffic and be at risk of getting rear ended by some inattentive car driver. In fact a lot of riders here own one with the sole use of cutting through the ever increasing rush hour traffic jams, in order to get to and from work and home a bit quicker than is possible on four wheels.
When done correctly and at no more than 15-20 mph faster than the other traffic using the road, it is perfectly safe.
By correctly I mean by riding defensively. As you should be doing at all times on the roads anyway.
Riding defensively does not prevent us from riding progressively. It is all about spotting potential issues ahead and dealing with them before they become a problem.
Filtering through is simply a much safer and progressive place for us to be located in the the traffic stream.
Most car, van and truck drivers here will move over and give us motorcyclists a little more room to filter through when the traffic is stationary or slow moving. That is if they see us in their mirrors. Usually the main reason they don't see us, is that they don't check their mirrors often enough, hence a loud exhaust or a little blip of the throttle to let them know we are there and coming through is not usually a big issue.
My view is, filtering on motorcycles should be absolutely legal everywhere in the world. Hope you can get this law passed.
