Yea, same here. I signal before the right turn lane appears and then move into it ASAP. I always take the full lane in those cases.

The case I hate the most is when the (through or right) bike lane is to the right of a right turn lane. That's a tough call for me. Sometimes I stay in the bike lane and move up in front of cars and make eye contact to make sure they aren't going to turn right into me, but if they aren't stopped I prefer to take the right-most through traffic lane through the intersection and move over as soon as I can.

Some people will honk & flip you off regardless of what you do. I just smile and wave, to thank them for seeing me if nothing else.

BTW, it isn't 'his' lane, it's your right turn lane too. Just be courteous and confident and most people will respect you.
