Los Angeles is about to throw a party for a train that arrives two decades late and several billion dollars over budget. The narrative being fed to the public is one of "connectivity" and "historic milestones." In reality, the opening of the D Line extension to Beverly Hills is a textbook example of sunk cost fallacy masquerading as progress.
We are told that digging a hole under Wilshire Boulevard will somehow solve the existential crisis of Southern California mobility. It won't. I have spent years watching municipal agencies burn through capital on 19th-century solutions for 21st-century problems. The Wilshire subway isn't the "backbone" of the city; it is an expensive, rigid tube that ignores how people actually live, work, and move in 2026.
The Myth of the "High-Capacity" Savior
The lazy consensus among urban planners is that subways are the gold standard because they move the most people per hour. On paper, $9,000$ to $12,000$ passengers per hour sounds impressive. But capacity is a vanity metric if the utility is non-existent.
The "Purple Line" (D Line) extension assumes a hub-and-spoke model of commuting that died in 2020. People no longer flood into a single central business district at 8:00 AM and exit at 5:00 PM. Work is distributed. Errands are multi-stop. A fixed rail line is the most inflexible tool in the shed. If your destination is even half a mile from the station, the "last-mile" friction in Los Angeles—a city designed to be hostile to pedestrians—makes the entire trip a net loss in time compared to a mediocre Uber ride.
Geometry is Not Destiny
Proponents point to the density of Wilshire Boulevard as the ultimate justification. They cite the "linear city" theory. But they ignore the cost-per-mile reality. We are spending roughly $1 billion per mile.
For that same billion dollars, the city could have implemented a world-class Bus Rapid Transit (BRT) network covering the entire Westside. We could have had dedicated, physically separated lanes, signal priority, and high-frequency electric buses on every major arterial from Sunset to Washington Boulevard.
Instead, we chose to go underground because of a psychological obsession with "heavy rail." There is a certain prestige attached to subways that politicians crave. You can't cut a ribbon on a bus lane with the same cinematic flair. But while the subway serves one specific corridor, the rest of the city remains a transit desert.
The Beverly Hills Bottleneck
Let’s talk about the specific "victory" of reaching Beverly Hills. For decades, the NIMBY (Not In My Backyard) resistance in 90210 was framed as the primary villain. Now that the tunneling is done, the narrative is that the "walls have come down."
That is a fantasy.
A subway station at Wilshire and Reeves doesn't change the fact that Beverly Hills is zoned to resist the very density that makes subways functional. If you don't have high-density housing and mixed-use development within a five-minute walk of the platform, you aren't building a transit system; you're building a very expensive elevator for a handful of boutique shoppers and office workers who will still likely drive their Porsches to the parking garage.
To make this subway work, you would need to bulldoze half of the low-slung luxury storefronts and replace them with twenty-story residential towers. Is that happening? No. The "historic opening" is a hollow victory because the land use around the stations remains stuck in 1975.
The Maintenance Debt Trap
The true cost of the Wilshire subway isn't the construction; it's the inevitable decay.
LA Metro has a track record of prioritizing "shiny new things" over the basic upkeep of existing lines. If you've ridden the B Line (Red Line) lately, you know the score: broken elevators, security concerns, and a general sense of abandonment. By adding the massive operational overhead of the D Line extension, Metro is effectively cannibalizing its ability to maintain the rest of the system.
We are building a house we cannot afford to clean. In a decade, when the stations are grimy and the headways start to slip because of "budgetary constraints," remember that we chose this. We chose the most expensive possible mode of transport in an era where micro-mobility and autonomous shuttles are proving that flexibility is more valuable than raw tonnage.
The Physics of Failure
Consider the energy expenditure. Moving a multi-ton train car to transport thirty people during off-peak hours is a thermodynamic disaster.
- Subway Car Weight: ~80,000 lbs.
- Average Off-Peak Occupancy: 20-40 people.
- Energy per Passenger Mile: Significantly higher than a modern EV or e-bus in non-peak scenarios.
The "green" argument for the subway only holds water if the trains are at $80%$ capacity or higher. Given the shift toward hybrid work, those numbers are increasingly rare outside of a few hours a day. We are running a heavy industrial machine to solve a software problem.
What People Also Ask (and Why They’re Wrong)
"Won't this significantly reduce traffic on the 10 and 405?"
No. It never does. This is the phenomenon of Induced Demand. If you remove five hundred cars from Wilshire Boulevard because those drivers took the train, five hundred other drivers who were previously avoiding Wilshire will now take those spots. Traffic is a gas; it expands to fill the container. You do not fix traffic by adding a train; you fix traffic by pricing the road. But no politician has the spine to implement congestion pricing, so we dig holes instead.
"Isn't LA becoming more like New York or London?"
L.A. is $500$ square miles of sprawl. New York is a series of islands. You cannot "New York" your way out of Los Angeles's geography with three new stations in Beverly Hills. The scale is wrong. The density is wrong. The culture of "point-to-point" travel is too deeply baked into the California DNA.
The Better Path We Ignored
Imagine a scenario where we didn't spend $9 billion on nine miles of track.
Imagine $9 billion invested into:
- A universal e-bike subsidy: Giving every resident a high-quality e-bike for free would have cost less and moved more people.
- Automated Micro-Transit: A fleet of thousands of autonomous, six-passenger shuttles that provide door-to-door service to existing transit hubs.
- Total Bus Prioritization: Making every major boulevard "Bus Only" with $1$ minute frequencies.
Those solutions are "ugly." They involve taking space away from cars on the surface, which triggers the voting public. Subways are the "coward’s way out" of urban planning. They allow politicians to claim they are helping transit without ever having to tell a driver they can't have their fourth lane.
The Hard Truth of $2026$
The Wilshire subway is a monument to the way we used to think about cities. It treats the human being as a predictable unit that travels in a straight line to a skyscraper. But the modern worker is a nomad. They need to go from the coffee shop to the co-working space, then to the gym, then to a grocery store, and then home.
A train that stops every mile and requires a twenty-minute walk at either end is an insult to their time.
We are celebrating the completion of a project that was designed for a world that no longer exists. We have traded billions of dollars for a press release and a ribbon-cutting ceremony. The ridership numbers will likely underperform, the maintenance costs will skyrocket, and the traffic on Wilshire will remain exactly as soul-crushing as it was before the first shovel hit the dirt.
Stop applauding the hole in the ground. Start asking why we are still using $1950$s logic to solve a $2026$ reality.
If you want to move Los Angeles, stop digging. Start reclaiming the streets we already have.
