I found that if you cut to the left sharply while making the turn, you'll shorten the distance traveled and actually find yourself waiting for the car ahead of you to move forward. That gives me plenty of time to slowly merge right, back onto the shoulder. That is if you actually ride on the shoulder, many riders are too prideful for that, and opt to stay in the middle of the traffic lane. Not that there's anything WRONG with that, I just feel safer out of the traffic lane when traffic is going faster than I am. Weird, I know . . .
