Pull over. Wait on the side of the road for two songs on your CD player - two great songs you love. In the six or seven minutes this takes you will have relaxed and now be in a better mood ... but best of all, it'll take five minutes to catch up to those people going slow and nine times out of ten people going this slow are locals - and they will have gone into a property or turned at a crossing.
Try it sometime. They win if you get angry. We all win if you're not on the wrong side of the road with veins bulging from your forehead when I'm coming the other way.
