This is very, very wasteful compared to actual mass transit. A subway network is much more effective at delivering people.<p>If he&#x27;s looking for mega-good, Musk would do significantly better to drop a full subway network.<p>edit: tunnelling is a broadly solved problem. It&#x27;s difficult, expensive, slow, etc. But there&#x27;s no engineering reason why a hole in the ground can&#x27;t happen. Musk might be able to drive some significant improvements there. No idea. But tunneling itself is not a reason to knock an idea beyond the cost and geoengineering involved.
