Re: "The Hitchhiker’s Guide to the Galaxy had hyperspace..."
I believe Arthur and Ford once (in one version of HHG2TG that is) managed to hitch a ride through time itself via one Chestfield Sofa if I recall, it was only then that they decided to travel onwards via BistroMaths.
So I suppose we can deduce that Chesterfield Sofa's are the vehicle of choice for really long journeys, whilst your mobile French Cafe would do for a little runabout for the wife?
