Wrong, on everyone of these you have to enter the roundabout and then take the 
next exit, it is not a graceful sweep.

We are creating a map, not a geometrical reality picture.  The ways we enter 
need to be topographically correct and in this case they are not.

Your also looking at it as if the roundabout joins the roads, where as the 
roads join the roundabout.
