> Some roundabouts have the center circle partially paved This is the "truck apron". Virtually every roundabout in our town has one, and it's up a little curb to get onto it. A little too much for cars to sensible abuse, but a dirt motorbike gets over them easily. :) Also when it snows in people can't tell where the apron starts, so traffic tends to cut over it.
