A pedantic review of the Las Vegas loop

Original Article ↗ Hacker News Discussion ↗

Overall view of the Las Vegas Loop / Boring Company

  • Many see tunneling as a mature, optimized industry; they argue Boring Company has not delivered real innovation beyond slightly smaller, less-equipped tunnels.
  • Defenders say it’s too early to call it a failure: founded 2017, first contract 2019, system delivered as specified and cheaply versus competing local bids.

Cost and construction comparisons

  • One side claims the LVCC tunnel was more expensive and slower per km than major rail tunnels; others counter with numbers showing the LVCC per‑mile cost far below the Channel Tunnel and typical US subway costs.
  • There is confusion over exact LVCC/Vegas Loop costs (52.5M vs ~106M, 1.7 vs 2.2 miles, additional stations); commenters note a lack of transparent breakdown of tunnel vs station vs vehicle costs.
  • Several point out station construction usually dominates total cost, so savings on tunnel diameter may not matter much.

Capacity and geometry

  • Strong criticism: small pods/cars in single-lane tunnels are inherently low throughput compared to trains in similarly sized tunnels, which can move tens of thousands of passengers per hour.
  • Multiple back‑of‑the‑envelope comparisons show needing enormous tunnel length or many parallel tunnels to match a single high‑frequency subway line.
  • Supporters respond that:
    • More numerous, cheaper tunnels can offset per‑tunnel capacity limits.
    • Point‑to‑point service and smaller stations may be better for many US use cases than “crush‑loaded” subway trains.
    • The system is more comparable to light rail or commuter links than to top-tier metros.

Automation and operations

  • Many are surprised the cars have human drivers; some assumed Autopilot would be used in this highly constrained environment.
  • Skeptics argue that reliable automated control is hard and safety‑critical, even on rails; supporters say metro automation was “solved” decades ago.
  • A small, unimpressive operations control center is noted; some see this as penny‑pinching, others say it’s typical of municipal control rooms and not a major cost.

Safety, fire, and worker protection

  • The operations manual reportedly devotes more space to scripts about the company and its flamethrower than to fire procedures, which some read as emblematic mis‑prioritization.
  • Concerns:
    • No emergency egress corridors; single-lane tunnels with no easy way around a disabled vehicle.
    • Lithium‑ion battery fires in enclosed tunnels.
    • Reported construction injuries and chemical burns; debate over whether this is unusually bad or typical of construction.
  • Others argue risk is mitigated by:
    • Small, isolated passenger vehicles rather than mixed heavy trucks and cars.
    • Vehicle features like HEPA‑filtered, pressurized cabins (as claimed in the thread).

Public vs private transit and equity

  • Several criticize the concept as a “luxury” or marketing‑driven system for convention visitors and high‑end tourists, not serious mass transit.
  • There is philosophical pushback against privatized urban transport infrastructure, with comparisons to high‑toll private roads near US cities.
  • Supporters counter that:
    • It doesn’t displace public transit and uses private capital.
    • It could evolve from Tesla taxis into higher‑capacity rubber‑tired metro‑like service over time.

Conceptual critiques

  • Repeated comparison to just “roads in tunnels with taxis”: many argue this reinvented concept can’t match rail’s geometric efficiency.
  • Others, drawing on personal rapid transit experience, claim that dense networks of small automated vehicles can be competitive on seat‑mile efficiency up to the scale of major urban rail, while offering direct, no‑transfer trips.
