Thanks, 5jj. Lovely, with all the animated cartoons and explanations. I'll keep it in Favourites for the next time I sit a driving test.

May I add, though, that the parallel parking test over there is a piece of cake. Two car lengths is heaven. In B.A. they give you one car lenght plus one metre*. And mind that you park exactly 20 cm from the kerb. Honestly, that's next to impossible for clumsy** people like me.

* about three and a half ft.
** There ought to be one of those xxx-impaired words for this We clumsy have our dignity, too.
