I don't split lanes because there's no 2 lane (in the same direction) road on my commute (or anywhere else I ride for that matter). But if I'm filtering forward, the only thing I've ever had happen is that if someone notices me, they move RIGHT to try to stop me. Doesn't work unless they're willing to drive all the way out into the ditch.
But I don't filter much anyway; I prefer to change my ride times until I'm riding when there's hardly any traffic.
