To do that with his tunnel-based concept he’ll have to solve big technical and cost challenges. Experts are skeptical. Musk’s pitch is that The Boring Co. can build transportation-oriented tunnels faster and cheaper than current technology, mainly because his machines will drill them at about half the diameter of those for subways.

This significantly reduces the cost of lining the tunnel, and makes them suitable to use in heavily urbanized areas. The major disadvantage is the upfront cost. TBMs are expensive to construct, and can be difficult to transport. The longer the tunnel, the less the relative cost of tunnel boring machines versus drill and blast methods.
