John Oliver from the Daily Show poked fun at Elon Musk’s Hyperloop tonight (the futuristic proposal of a tube for 800 mph/ 30 mins of travel from San Francisco to Los Angeles). ‘It’s a cross between a Concorde, a rail gun and an air hockey table’, says Mr Musk. He is criticizing the current high speed rail plans as ‘too expensive and too slow’ but says he cannot take on the Hyperloop right now. He has his hands full with building rockets and Teslas.
