Personal Pod Transport: A Cost Analysis of What We Could Have Had

The premise

A go-kart sized electric pod. You lie in it, wear a helmet. It runs on a guided track like a slot car. No driver, no steering, no human error. The track manages everything.

The numbers

Pod cost

| Component | Cost | |---|---| | Electric go-kart chassis | $2-3k | | Lie-down shell/fairing | $1-2k | | Helmet | $100 | | Motor, battery, electronics | $2k | | Total per pod | $5-8k |

Less than a wheelchair. A tenth of a cheap car.

Track cost (ground level, like a bike lane with rails)

  • Guide rails + flat surface: $1-3M per km
  • Comparable to existing bike lane infrastructure
  • Could go where bike lanes already go or are planned
  • Track cost (lightweight elevated)

  • Traditional monorail: $10-50M/km (because it carries 50,000kg trains)
  • Pod track carries 150kg. Not the same engineering problem.
  • Lightweight elevated: $3-8M per km
  • For reference: a normal road costs $2-10M per km anyway
  • Suburb-scale deployment

    | Component | Cost | |---|---| | 20km ground-level track | $40-60M | | 200 pods | $1-1.5M | | Control system & software | $2-3M | | Total per suburb | ~$50M |

    Perth metro scale

  • ~200km of track to meaningfully connect the metro area
  • Total: ~$500M-$1B
  • The comparison that should make you angry

    Perth Metronet extension: $5.7 billion

    $5.7B ÷ $50M per suburb = 114 suburbs covered

    Perth has ~250 suburbs. That one train project could have given nearly half of Perth point-to-point, on-demand personal transport.

    All of Perth (250 suburbs): ~$12.5B. Roughly two Metronets.

    What Metronet delivers: trains on fixed routes, fixed schedules, to fixed stations you drive
