The advantage of the Volksjager was it's ease of use matched with unbeatable speed (the BMW engine could reach around 520 miles per hour). The "People's Fighter" was to be mass produced and introduced to the Hitler Youth, who after a brief training, could fly the easy to manage plane.
Production of the Volksjager began in bomb-proof underground bunkers (below), though at this point the war was past the turning point for the Nazis, and the impact of Luftwaffe jets was trivial.
Thankfully the He-162 Volksjager never took hold... I think we're better off with the Volkswagen, anyhow.
