BMW announced a new technological innovation that would be incorporated into future versions of its cars—the badgewash system. No longer would BMW drivers have to endure dirt on their enamel bonnet badge. The advertisement claimed that, "A tiny sensor mounted in the wiper arm measures the light reflected back from the white sections of the BMW badge… Even if a film of dirt cuts out as little as 5% of that light, the sensor will detect it and start the wiper."
