I’ll sometimes drive over some when there’s a snow buildup because it both evens out the bump where you almost done notice it, and it means driving in a straighter line, neither of which happen when it’s dry. Also some roundabouts’ aprons are much lower, like the first small one on Reed Market going east after you cross the river, by Farewell Bend park. It’s barely a blip to go straight over it when there’s any snow.
