Hyperloop

Some say that Elon Musk’s gone too far with this whole “hyperloop” idea.
Which is why he was smiling wide for the cameras as he unveiled his gleaming hyperloop test track.
A miles-long vacuum-sealed tube through which a passenger cabin would race at thousands of miles per hour.
He ushered the press into the cabin, stepped outside, and slammed the door shut.
“How does it slow down?” asked a reporter through the window.
“I’ll show you,” said Musk.
Then he pressed the Go button.
The cabin leapt forward, and zoomed away down the track.
“It doesn’t,” he grinned. “Good riddance.”
