| Some people say Basingstoke is good for roundabouts but Hemel Hempstead has the one and only Magic Roundabout. This is a large roundabout which has a series of small roundabouts at every entrance and exit. The scariest effect of this is that the mega-roundabout is actually a two-way road.
e.g.
\\ | | //
X===X===X
// \\
===X X===
\\ //
X===X===X
// | | \\
I guess that looks rather like a carbon ring but I'm afraid drawing the 7th roundabout was beyond my skill.
