Before I ever get around to throwing things at the TV, I remind myself that they have the term Routemaster Moments, to belittle transport buffs who write in and complain about Routemaster buses, for example, appearing in London based dramas of the wrong decade. I suppose as long as they cover up the yellow line road markings with straw, or fake snow, on Thomas Hardy or Jane Austen dramas, perhaps we should just let it go.
