First time I drove abroad, I had a post it note on the dashboard - a diagram of a roundabout with an arrow pointing out the direction.
That was a few years ago, I'm much better now. Apart from Spainish roundabouts - I seem to have developed a habit of talking back to the satnav. It/she tells me to take the third exit, I talk back "on dos trays" - AKA Basil Faulty.....
