Most reviews of Elon Musk‘s hyperloop plan focus on technical questions. Will it cost as little as he estimates? Could it move as fast as he projects? Could the system work at all?
None of these are the real problem with the hyperloop. The real problem is how an infrastructure-heavy, point-to-point system can possibly compete with personal vehicles that can go just about anywhere–the United States has more than 4 million miles of public roads–or with an airline system that requires very little infrastructure and can serve far more destinations than the hyperloop.
Musk promises the hyperloop will be fast. But fast is meaningless if it doesn’t go where you want to go. Musk estimates that people travel about 6 million trips a year between the San Francisco and Los Angeles urban areas, where he wants to build his first hyperloop line. But these urban areas are not points: they are huge, each covering thousands of square miles of land.
