They're not. It's just a smaller diameter, so less spoils need to be removed and hauled away (trucking soil is actually hugely expensive and will only get moreso as gas increases in cost) and it's largely automated so it gets by with fewer of those costly union workers. That's pretty much the two biggest differences, it's very similar to a sewer tunnel.
Also it seems like his system is a "dumb tunnel, smart vehicle" system so there's very little inside the tunnel itself, no signals, tracks or power distribution, which means no substations, relay rooms, etc, just a pure tunnel. Plus, no expensive union workers to build those systems either. The only ancillary aspect is ventilation, which I'm sure authorities will require so that passengers don't suffocate in the event of a fire, and emergency exits so that passengers can escape and don't have to walk many miles to get out.

automatically see a reason to be skeptical here. I'm not the biggest fan of Musk, but I don't scoff either. Henry Ford and Thomas Edison were also douchebags with a cult of personality, but through a combination of business savvy, ambition and ruthlessness, as well as innovation, they still changed the lives of every human on the planet. Even in the fixed-guideway transit realm, we've seen plenty of unusual systems get designed and built without setting piles of money on fire. It's only in America that we're all so cynical about big projects, because we're so accustomed to a broken bidding/construction process and very inconsistent support for transportation from governments.
Also, I've said it before: people need to stop claiming that this is the future of public transit, because it won't work to move large numbers of people. Musk himself, as well as his fanbois are guilty of this. But it seems well-suited for a relatively small, niche group of travelers willing to pay top dollar for speed and efficiency - like, say, an airport express or a train to ski resorts. TBH, I'm not sure there is a business case in Detroit. Well-heeled business travelers might be going to downtown, but more likely they'e going to Auburn Hills, Farmington, Troy, etc.
