The funny thing is that during the event, Elon claimed that the car can recharge the tanks itself [0], but in the Top Gear video, the Tesla folks say that it is recharged from an external source [1]. In the Top Gear video, they also say that they are filling it from a "high pressure nitrogen system", whereas Elon claims that the tank is filled with air. They can't even keep their own messaging straight.
