I'll be fine with that as long as lane splitting is legal on my non-autonomous motorcycle. Since lane splitting is legal in CA, I wonder how well google's vehicles deal with other drivers that split lanes?
I've seen demonstrations where the autonomous car recognizes bicyclists and adjusts the travel path to avoid the "obstacle". I imagine with a motorcycle the autonomous car should always see it coming up behind it and could be programmed to give it some room as it gets close.
