This incident happened in late 1990s, when BMW was flooded with calls from German men saying they do not want to take directions from a woman; as a result of which, BMW was forced to recall the female-voiced navigation system on its 5 Series cars. What more, even BMW was guilty of sexism when their customer service representatives tried to calm down the callers by explaining that men were actually behind the making of both the car as well as the directions.
