I am not a mathematician or physician but I know for sure that speed is for real !
Just take a moment and enjoy some of Mercedes Benz historical land speed racers and race cars !
I had the opportunity to visit The Mercedes Benz museum in Stuttgart. It was extremely nice and inspiring and without going into details, the cars for speed and racing are fantastic. Such design and engineering meisterstück ! Well kept together via the thesis "Form und Funktion".
All except the two last picture are pre war and they make you think:
Make speed not war !
