Vehicle 0 in the diagram is your vehicle. You intend to travel straight through a roundabout. Motorcycle X approaches from your right and will cross your entry. Car Y from that same approach takes its first exit before your entry; car Z from the opposite approach also exits without crossing your path. Which must you give way to?
