Lane Splitting - what's the go?

[Volvi]

I split most of the time.

When stopped by a cop and he says you split lanes the only defensive answer is "Yes but only on the right side of the vehicles and when they were stationary and overtook them in the same lane when it was safe to do so" He may reply but you entered the alongside lane making overtaking the vehicles on that lane to the left of all the vehicles. "No sir i stuck within my lane only". (Bearing in mind just how much observation cud the cop have had of the lines) "When it was safe to do so" are the key words to.

I havent been stopped but was told by a cop thats the effective answer.
