You could say it is the most traditional PR technique of the whole automotive industry. > On 5 August 1888, 39-year-old Bertha Benz drove from Mannheim to Pforzheim with her sons Richard and Eugen, thirteen and fifteen years old respectively, in a Model III, without telling her husband and without permission of the authorities, thus becoming the first person to drive an automobile a significant distance, though illegally.
