How should a Class E driver negotiate a busy roundabout (rotonda) with an animal-drawn vehicle?

1. Drive across the center grass island
2. Yield right of way to all vehicles already circulating inside the roundabout, enter the outer right lane when a safe gap opens, maintain a steady pace, and signal exits with hand signals
3. Force circulating cars to stop by whipping the horse
4. Enter the roundabout going in the wrong direction (clockwise)
