Same here. I can't remember the last time I had any friction between myself and a vehicle while splittng past them, or them "splitting" past me. No more challenging or frightening than brushing my teeth.

I am starting to believe only cyclists who never split lanes are imagening problems that are rare and expressing those concerns here.

Filtering up along the right curb is a different matter. Plenty of dangers there. I split lanes to avoid those curbside dangers.
