"Hyperloop Passenger Capsule
The maximum width is 4.43 ft (1.35 m) and maximum height is 6.11 ft (1.10 m). With rounded corners, this is equivalent to a 15 ft2 (1.4 m2) frontal area, not including any propulsion or suspension components."
At a first look I didn't get that the proposed passenger capsule would be so small. That's pretty cramped.
Edit: Isn't the the ft to m conversion for the height wrong?
