I started with total number of cars sold globally, then tried to estimate what fraction might be autonomous by 2025.
Start by clarifying the scope: are we talking about global revenue, number of vehicles sold, or total addressable market? Then structure your answer by estimating the number of driverless cars on the road in 2025 and multiplying by an average revenue per vehicle or service. Use a top-down or bottom-up approach, state assumptions clearly, and sanity-check your final number.
Pro tip: Acknowledge that the market is still nascent and highly dependent on regulatory approval and technology readiness; showing awareness of these uncertainties demonstrates maturity. Also, tie your estimate to a specific segment (e.g., robotaxi vs. consumer-owned) to avoid overgeneralizing.
Ask whether 'market size' refers to revenue, unit sales, or number of vehicles in operation, and whether it's global or regional. This ensures you answer the right question.
Decide between top-down (e.g., total passenger vehicle market * penetration rate) or bottom-up (e.g., number of cities * vehicles per city). Pick one and justify it.
List key assumptions such as regulatory approval in major markets, technology readiness, and adoption rates. Use round numbers for ease of calculation.
Perform the math step-by-step, narrating your logic. For example, estimate the number of driverless cars and multiply by average annual revenue per car (if revenue-based).
Compare your estimate to known benchmarks (e.g., total auto market size) and discuss potential errors or ranges. Summarize your final answer with caveats.
