Yeah they were called the KDFwagen too then (strength trough joy car).
They switched to buildings then as little jeeps and invaded Russia instead of delivering the cars to the buyers. Pieche ran the factories with concentration labor after they ran out of hitler youth to exploit. And the British passed over the car when the war read over because conditions at the factory are so bad the cars were being built like shit initially.
Like that submarine.
Maybe it can crash into them while being full of them. Efficient way to up the numbers.
