When approaching a multi-lane roundabout on a motorcycle, why is proper lane positioning and signaling crucial?

1. Motorcycles are exempt from roundabout rules in Bahrain
2. Drivers in larger vehicles may cut across lanes; claiming your lane position firmly and indicating clearly prevents cars from squeezing into your space
3. To allow the rider to execute high-speed overtaking inside the roundabout
4. To signal pedestrians that the motorcycle will not stop
