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.
