Elon Musk found it rather tedious that he had to switch transportation vehicles if he wanted to sail, drive, or fly. So he decided one day that he would solve this problem for good. Using the parts of a 1983 Hurst Oldsmobile and his most recent tesla engine technology, Elon added a sail and a boat motor (sticking out the back) to propel the vehicle in water. He added a helicopter propeller as well as hovercar wheels to allow the vehicle to either fly through the air or hover slightly above ground to drive different places. the engine for these processes lies in the front carriage as opposed to the boat motor in the back.
