I've never had much trouble with U-turns. In the MSF class they had us doing figure eights in a box just a tiny bit bigger than a lane of traffic. I've gotten a lot better at riding since my MSF class! Besides which, my ninjette handles a hell of a lot better than the Honda Rebel I was on there. I can do a U-turn in the equivalent of a single lane of traffic without issue, so I'll start at the inside corner of the lane and end up in the middle-outside quadrant of my target lane.
Practice your low-speed maneuvering, guys! If my dumb ass can pull it off, you all can.
