Walk Through Walls! (Broken by updates)

Sadly with new physics updates to Medieval Engineers, this no longer works as you cannot make the cart move by running inside it. It was fun while it lasted!

Simply aim cart at a basic wall a little way back from it (the thin walls or a block wall, they both work). Get inside the cart, turn off flight and walk forwards straight through the wall without stopping. 5/5 times it has successfully worked for me, the cart breaks as the wall does and all you have to do is not let go of that w key and you'll be straight through the wall!
