Firstly, they drive on the right

ffs, everything’s in bloody kilometres, hardly any petrol stations and sometimes they have no fuel/ not open Sun& Monday and they might ask you to pay before you fill up . Don’t bother with GB sticker, you know your British and do expect them to speak English- if they don’t just talk slowly and louder. Don’t bother with carrying breathalysers or luminous arm bands and don’t expect anywhere to be open between 12-3 which is when Johnny Foreigner has lunch. The French do warn you of impending speed traps and tend to take you somewhere as opposed to just giving directions, and offer you a drink or a bed for the night. If you have a Guzzi the cops let you have run of the place.
