I believe CA is the only place its legal.As I watch that video I think to myself does his speedometer say "IDIOT"? I'm not a lane splitter as it's not legal here...that I'm aware of. I can see how it can be extremely advantageous...from an outsider peering in I can say this, HE'S OUT OF HIS GOURD!! Just don't hurt yourself guys.
*edit* Confirmed. Not legal in OK...at all...under any circumstance...
