Yes, but in this case you filter on the driver's left. You don't filter up in the 10cm between the curb and the car when the driver is signaling right; it's a dick move and eventually you're going to get hurt.

Fair enough, but honestly this seems like far less of a problem than the large fraction of drivers who don't know how to turn properly in the first place, and just make that right turn without having merged into the bike lane.

I commuted in SF for a year, and I'd guess 75% of cars don't know why the bike lane starts getting dashed before an intersection.
