if you're not lane sharing then isn't it cutting in line?
BTW, I'll stop between two cars in front of me if I'm uncomfortable about leaving my six exposed and I'm not filtering to the front.
I do this on double left turn lanes if I'm not able to filter all the way up. moron cagers don't know how to keep it in their lane while turning.
