Ruby, how about a RoadTrain up your ASS????
ASS as in AeroSuperSports
A: Those road trains cruise at at least 100 km/h. B: Given that the distance between service stations in the Northern Territory can be as much as 250 km there is a bit of a tendency to keep speed down for fuel economy.
A + B means that in a small open vehicle it takes a damn long time to pass all those wheels busily rotating at eye level! Passengers have been known to feel quite nervous.
