Well, at first I thought, a white Subaru Liberty. Then I had an idea of something more upmarket, but with extra safety features, say a Volvo station wagon (but with a 6-disc CD changer in the back, so he can listen to lots of gospel without being distracted by having to change discs.
But then I thought, no, it's obvious, the long hair, the beard, the sandals: it has to be one of those old Renaults that Australian high-school teachers and academics drove in the late 1970s.
So if you see one, wave. It might give you a leg up, one day. (And if it's a teacher, well, they need all the positive reinforcement they can get, too.)
