I've always said the two problems are lack of space between vehicles to safely "split lanes" and ignorance of motorcyclists in general and lane splitting specifically.
If there's really a lack of space, then you have to wait. But it's usually not a problem.
As I was riding home this afternoon, through downtown Seattle, north on I-5, rush hour traffic, I kept looking for situations where lane splitting would be advantageous. Not once did I experience a situation where it would have been safe, in my opinion, to ride between stopped or very slow lanes of traffic.
I've been on I-5 at the north end of Seattle. I recall taking the 520 across to I-5, to go up to Ravenna for the monthly Vintage Motorcycle Enthusiasts meeting at Teddy's on Roosevelt Ave. The traffic was always awful, and my R60/2 didn't much like it. I always wished I could split like I did when I lived in LA.
Another theory - perhaps your lanes are wider than our 1950s - 1960s era designed and built freeways?
Believe me, you've got plenty of room on I-5 to split. In LA, they've stolen pretty much all of the roadway to make lanes, so they range from not particularly wide to very narrow. Take a ride on the Arroyo Seco freeway (I-110) towards Pasadena from downtown. It was LA's first freeway, and the lanes are Model T sized.
The BEST time to split is when traffic is stopped. There are no spaces in adjacent lanes for people to jump across to. IMHO, the most dangerous time to split is when traffic is picking up, and there are staggered holes in the two left lanes. Almost certainly someone will decide they need to be in the other lane then. You're right that cars don't respect bikes, but cars usually respect cars, so splitting between two cars is a good bet and that is where I want to go.
Regarding speed, when traffic is completely stopped, I'm usually in 1st gear. When I get to the point that I'm starting to think about upshifting out of 2nd, that's when I get back in line.
In California, there's no actual law that governs how fast, or how much faster than the surrounding traffic, you can go. You'll hear all kinds of "rules", but the only one that matters is what the CHP officer says if he pulls you over. There are three or four sections they can use on you, none of which say anything at all about splitting. Things like unsafe speed or illegal lane change.
Do you have free HOV lanes open to motorcycles, allowing you to travel at the same speed as mass transit (Express buses)?
In the SF bay area, the HOV lanes are just the left lane with a diamond painted on them. They are restricted only certain hours of the day. This creates a certain amount of danger as people will jump into the HOV lane to get around some traffic and then jump back (because they don't want to be caught). In SoCal, the HOV lanes are generally separated by one or even two double yellow lines, and have only limited places to enter and exit. This can create a false sense of security, because people do ignore those double yellows and jump in and out, but it's much rarer.
I'm not aware of any completely separated HOV lanes down here like the I-5 and I-90 reversable express lanes.
