Final answer:
When driving through a roundabout, you should use the right lane.
Step-by-step explanation:
Generally, one might use the right lane to go straight, but this depends on the country and the specific roundabout design. In some places, the middle lane might be used for going straight, if the roundabout has multiple lanes and the signage indicates such. It is also essential to pay attention to road signs which might provide guidance on lane usage.
Examples given in the reference information, such as the rabbit attempting to cross the freeway, or race cars taking an inside path on a track's curve, emphasize the importance of understanding dynamics and rules of motion on roadways, which can be applied to understand roundabout navigation.
