A rider is in a roundabout and a car wants to enter from the right. The rider is already circulating inside. Which answer best combines DGT roundabout and moped-defensive guidance?

1. The rider has priority but should still be visible, predictable, and ready for the car's mistake
2. The car has priority because it is on the right
3. The moped must stop inside the roundabout for every entering vehicle
4. The rider should accelerate aggressively to prove priority
