Roundabout Setup

To connect a road to a roundabout is pretty straightforward.

Select a waypoint where you want your car to exit and connect that point to a road. No other settings are required, cars will randomly choose one of the waypoints to continue driving.

For the waypoints that enter (the ones marked with a green line), you should mark them as give way so the vehicles should stop there and wait until the roundabout is free.

If you have multiple-lane road, do not connect both of the lanes to the same point as below.

This is wrong because if you have 2 vehicles at the green points, they will never continue thinking that from the other lane, a car is coming and it should give way before continuing.
