Could the Hyperloop Really Cost $6 Billion? Critics Say No

Keeping the same assumptions as the paper [1], if the cost goes from $6 billion to $100 billion, the amortized cost per ticket goes from $20 to $333 (!). As pointed out elsewhere [2], the capacity is extremely low, less than 1/10th that of the high-speed rail proposal (7.4 million vs. 95 million riders annually).
