Years ago my son and I followed two Minis up I-5, an Austin 850 in the right lane and an early BMW to it's left. It was an interesting comparison. Now the Countryman Mini is larger than a Land Rover [citation needed,
this one is three years old]
When Detroit responded to the Beetle/Renault Dauphine/Vauxhall the result was the 'compact' Falcon/Corvair/Valiant. Japan then countered with the Datsun 510.
