Waymo in Singapore

šŸ“ Discussion Summary (Click to expand)

Three prevalent themes in the discussion

  1. Car ownership is extremely expensive and functions as a status symbol
  2. The Certificate of Entitlement (COE) and associated taxes push the price of a basic car well over S$180,000, making ownership a luxury that signals success.

    ā€œOwning a car in Singapore is extremely expensive, basically meaning that if you can afford that, ā€˜you made it’.ā€ – ExoticPearTree
    ā€œA basic commuter car costs over S180,000 (US$135,000) due to a compulsory 10‑year quota license (COE) that alone costs S$100,000+.ā€ – shell0x

  3. Despite the cost, private cars provide tangible convenience (especially for families, weather, and flexibility)

  4. Many commenters note that owning a car avoids sweaty walks, waiting for rideshare, and the hassle of car seats, and it offers freedom to store belongings.

    ā€œHaving your own car is convenient, especially with kids, since you can keep stuff in the car.ā€ – eru
    ā€œThe ease and freedom of owning your own transport is still hard to beat… it removes the walk from bus/subway stations under the tropical sun, humidity; and the wait … of waiting for your uber/taxi driver.ā€ – fhe

  5. Waymo’s autonomous ride‑hailing could reshape Singapore’s mobility landscape, coexisting with existing transport while raising questions about taxi drivers and government control

  6. The planned 2028 launch is seen as a measured step that may alleviate future driver shortages, but it also sparks debate over its impact on incumbent taxi services and the broader goal of reducing private car use.

    ā€œWaymo said it will introduce its fully autonomous, all‑electric ride‑hailing service in Singapore via the Waymo app by 2028.ā€ – original post
    ā€œSingapore will do what they always do… take a measured approach and control every aspect of the roll out… they’ve already modeled a shortfall in taxi drivers in the future.ā€ – zhivota
    ā€œPotential, sure. Is it likely? No. Singapore does pretty well with the COE system and congestion charge.ā€ – eru


šŸš€ Project Ideas

KidSeat Match

Summary

  • A mobile app that aggregates real-time availability of child car seats in taxis and ride‑hailing vehicles (Grab/Gojek) and lets parents book rides with guaranteed seats.
  • Eliminates the uncertainty and safety concerns highlighted by users debating car‑seat exemptions and the inconvenience of traveling with kids in Singapore’s hot, humid climate.

Details

| Target Audience | Parents with young children who rely on taxis/ride‑hail for short trips, especially families without a private car. | | Core Feature | Live map showing nearby vehicles with installed car seats, one‑tap booking, and optional seat‑inspection verification via driver photo. | | Tech Stack | React Native (frontend), Node.js/Express (backend), Firebase Firestore for real‑time data, Google Maps SDK, optional QR‑code verification. | | Difficulty | Medium | | Monetization | Revenue-ready: $0.20 per successful booking fee + premium subscription for priority matching ($4.99/mo). |

Notes

  • Addresses red369’s question: ā€œAre taxis exempt, but car‑sharing like Grab not exempt?ā€ by giving parents a reliable way to find compliant rides. (HN: ā€œred369: Are taxis exempt, but car‑sharing like Grab not exempt?ā€)
  • Encourages shift from private car ownership to shared mobility for family trips, reducing COE demand and congestion. Potential for partnership with LTA and Grab to expand data coverage.

COE Pulse

Summary

  • A dashboard and predictive analytics service that tracks historical COE prices, auction trends, and provides bidding recommendations for individuals and small fleet operators.
  • Helps users navigate the opaque, high‑stakes COE system, reducing overpayment and anxiety about the $100k+ quota license.

Details

| Target Audience | Prospective car buyers, small‑business fleet managers, and expats evaluating car ownership in Singapore. | | Core Feature | Real‑time COE price chart, AI‑driven forecast of next auction price, optimal bid‑amount calculator, and alerts when price dips below user‑set threshold. | | Tech Stack | Python (data pipelines, Prophet/LSTM forecasting), PostgreSQL, React + Chart.js frontend, hosted on Vercel/Heroku, integrates with LTA’s published COE results via API scraping. | | Difficulty | Medium | | Monetization | Revenue-ready: Freemium model – free basic charts; premium tier $9.99/mo for forecasts, bid alerts, and portfolio tracking. |

Notes

  • Directly tackles eru’s comment about COE adjusting supply/demand: ā€œthe total number of cars in Singapore is fixed, and ownership cost adjusts (via the CoE auction) to balance supply and demand.ā€ (HN: eru)
  • Gives users data‑driven leverage in a market dominated by opaque bidding, sparking discussion on transparency and could be expanded to include ERP and parking cost forecasts.

CoolWalk SG

Summary

  • A network of air‑conditioned, shaded pod shuttles that provide comfortable last‑mile transport from MRT stations to residential/office buildings in Singapore’s hot, humid climate.
  • Reduces the temptation to use private cars for short trips by offering a pleasant, affordable alternative that mitigates heat‑related discomfort and encourages public‑transport use.

Details

| Target Audience | Commuters who avoid walking or cycling due to heat/humidity (e.g., professionals, elderly, families) and building managers seeking tenant amenities. | | Core Feature | On‑demand, electrically powered pods with climate control, UV‑shielded roof, and QR‑code booking via an app; pods run fixed short loops linking MRT exits to key drop‑off points. | | Tech Stack | Embedded Linux on pod hardware (Raspberry Pi 4), Flutter app for user-facing UI, AWS IoT for fleet management, Google Maps for routing, solar‑assisted charging stations. | | Difficulty | High | | Monetization | Revenue-ready: $0.50 per pod ride (distance‑based) + corporate sponsorships for branded pods; optional monthly pass $29.99/unlimited rides. |

Notes

  • Responds to delta_p_delta_x’s lament: ā€œWalking is not always an option if you need to be presentable wherever you're goingā€ and the desire to reduce land devoted to roads. (HN: delta_p_delta_x)
  • Provides a tangible way to test the ā€œcar‑liteā€ vision without requiring massive infrastructure; pilot projects could be launched in areas like Orchard Road or Tampines, generating measurable impact on short‑trip car usage and sparking public debate on urban micro‑mobility.
