August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive.[23] Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer.
