Stems presumably from the fact that to the average person in the street, the company is known for one (very famous) product and that there’s nothing particularly obvious about either name that says “company” or “product”. In terms of the first of those, for a long time “VW” basically meant “Beetle” (unless you were in to Campervans) - accurately reflecting company history if not current model range.The term "Robin Reliant" is very irritating. You wouldn't go around saying that you drive a "Mondeo Ford"![]()
