Tesla vs The Boring Company: Which Musk Venture Will Transform Cities More? | Taha Abbasi

Tesla vs The Boring Company — Two Visions for Transforming Cities

When people think of Elon Musk’s transportation revolution, they think Tesla. Electric vehicles, autonomous driving, robotaxis — these are the headlines that dominate tech coverage. But Taha Abbasi argues that The Boring Company may ultimately have a bigger impact on how cities function than anything Tesla produces above ground. With the Nashville Music City Loop project targeting tunnel construction costs of just $25 million per mile — a 95% reduction from industry averages — The Boring Company is quietly building the infrastructure layer that could make autonomous vehicles truly transformative.

The Cost Revolution Beneath Our Feet

According to analysis shared by tech watcher Aakash Gupta on X, The Boring Company’s Nashville project economics are staggering. The 13 miles of twin tunnels in the Music City Loop are projected to cost between $240 million and $300 million total — approximately $25 million per mile. Compare this to Nashville’s 2018 light rail proposal at roughly $200 million per mile, New York’s East Side Access at approximately $3.5 billion per mile, or Los Angeles Metro expansion projects approaching $1 billion per mile.

Even Musk himself responded to the analysis on X, stating simply that “Tunnels are so underrated.” It’s a characteristically understated comment about what could be the most disruptive infrastructure technology since the interstate highway system. Taha Abbasi, who has followed Musk’s ventures across Tesla, SpaceX, and The Boring Company, sees tunnel cost reduction as potentially more impactful than electric vehicles because it addresses the fundamental constraint that limits all urban transportation: surface space.

How The Boring Company Achieves 95% Cost Reduction

Several technical departures from conventional tunneling allow The Boring Company to dramatically lower costs. First, their tunnels use a smaller 12-foot diameter compared to the 20-30 foot diameters typical of subway tunnels. This smaller bore requires less material excavation, less structural reinforcement, and enables faster boring speeds. Second, their fully electric Prufrock tunnel boring machines are designed to mine continuously with no personnel inside the tunnel, dramatically reducing labor costs and safety overhead.

Third — and perhaps most innovatively — the Prufrock machines can “porpoise,” meaning they can launch and retrieve from the surface without requiring expensive launch pits. Traditional tunnel boring machines require massive construction staging areas at each end, which in urban environments can cost tens of millions of dollars just for the surface infrastructure. The Boring Company’s porpoising capability eliminates this requirement entirely.

Why Tunnels + Autonomy = The Real Revolution

Here’s where the Tesla and Boring Company visions converge. Autonomous vehicles operating on surface roads face enormous complexity: pedestrians, cyclists, construction zones, weather, traffic signals, and the infinite variety of human driving behavior. Autonomous vehicles operating in tunnels face almost none of these challenges. The environment is controlled, predictable, and weather-independent.

The Las Vegas Convention Center Loop — The Boring Company’s first commercial project — already demonstrates this. Tesla vehicles carry passengers through underground tunnels at the convention center, and the system has transported millions of passengers safely. While the Las Vegas Loop currently uses human drivers, the controlled tunnel environment is arguably the most logical first deployment for fully autonomous vehicle operation.

The Nashville Music City Loop — A Template for American Cities

Nashville’s Music City Loop project represents the next evolution of The Boring Company’s approach. The 13-mile twin tunnel system would connect key destinations across the city, providing congestion-free transportation in a metropolitan area that has been struggling with explosive growth and worsening traffic. The project received Federal Highway Administration (FHWA) approval and Tennessee Department of Transportation (TDOT) support, marking significant regulatory milestones.

If Nashville succeeds, it creates a replicable template for other mid-size American cities facing similar congestion challenges. Cities like Austin, Charlotte, Raleigh, and Denver — all experiencing rapid population growth without adequate transit infrastructure — could benefit from The Boring Company’s cost-effective tunneling approach. Taha Abbasi has covered the regulatory progress of the Nashville project and sees it as a proof of concept for the entire industry.

Surface Roads vs Underground — The Capacity Argument

Surface road capacity in American cities is essentially fixed. Adding lanes is prohibitively expensive, environmentally destructive, and often counterproductive (induced demand means new lanes fill up quickly). Underground tunnels add capacity without consuming any surface space, without displacing communities, and without the environmental disruption of surface construction. A network of Boring Company tunnels could multiply a city’s transportation capacity by 2-3x without changing a single surface road.

The Skeptics and Their Valid Concerns

Not everyone is convinced. Critics point out that The Boring Company’s Las Vegas Loop carries far fewer passengers per hour than a traditional subway system. They note that the company’s timeline promises have been optimistic, and that the jump from convention center tunnels to city-wide transportation networks involves orders of magnitude more complexity. Geology varies dramatically between cities. Utility conflicts are unpredictable. Community opposition can delay or kill projects.

These concerns are legitimate. But they miss the fundamental point: even if The Boring Company’s tunnels carry fewer people per mile than a subway, they cost 95% less to build. The economics change the equation entirely. A city might need five Boring Company tunnels to match one subway line’s capacity, but five tunnels at $25 million per mile ($125M/mile total) still costs less than one subway at $200 million to $3.5 billion per mile.

Which Musk Venture Changes Cities More?

Taha Abbasi‘s analysis suggests that while Tesla gets the headlines, The Boring Company may ultimately have the larger impact on urban life. Tesla changes what vehicles can do. The Boring Company changes where vehicles can go. Together, they represent a comprehensive reimagining of urban transportation — one that could make traffic congestion, surface parking lots, and hour-long commutes relics of the past.

The answer to which venture matters more may ultimately be “both, together.” Autonomous Teslas in Boring Company tunnels could provide the kind of efficient, affordable, on-demand transportation that public transit has always promised but rarely delivered. And at $25 million per mile, the infrastructure is finally affordable enough to actually build at scale.
