Elon Musk Unveils Boring Co's First Tunnel
&gt; &quot;Still, the $10 million is orders of magnitude lower than a typical subway project, Musk said.&quot;<p>Umm, and the capacity of these tunnels is also orders of magnitude lower than a subway. It would also be a lot harder to use and available to far fewer people. This entire idea should be laughed out of existence, but despite everything, Musk still gets fawning coverage for any crazy idea he spouts.<p>Maintenance will be impossible. Breakdowns of any sort would go from being annoyances to a few to being catastrophic failures for the system. Even if the tunnels never degraded, even if no car ever had a flat tire in the middle of the tunnel, and even if you could actually achieve 150mph (which would be extremely unpleasant for the passengers anyway), you couldn&#x27;t physically fit enough cars through the tunnel to compare to real transit system. Given that this thing requires rigging something up to your vehicle, the onload and offload points would immediately become major bottlenecks to any serious throughput even if you could cram them in bumper to bumper.
