Tesla CEO Elon Musk responded to a tweet of a GIF showing a car hovering above the ground saying, "[N]ew Roadster will actually do something like this." Musk explained the Roadster will use "SpaceX cold gas thruster system with ultra high-pressure air in a composite over-wrapped pressure vessel" to float. "I feel like you’re not joking," YouTuber Marques Brownlee commented.
