It gets better. The route to the airfield passes all the turn-offs for Heathrow airport, so is always very busy. But thanks to that volcano I set off in Iceland a few weeks ago there was absolutely no airport traffic, so I enjoyed living in one of those 1930s photographs of the Autobahn - a perfect arrow-straight road populated by a single distant descendant of the Beetle. On this, and the winding backroads that followed, the Spyder was as superb as it is silly.
