Guesstimates - Example 4 - Estimate the Number of Driver Less Cars in US by 2030

🔍 Clarifying Assumptions:

• Market size is based on number of users, not revenue.

• By 2030, it’s safe to assume technological and legal readiness for fully autonomous vehicles.

• Focus is on personal-use driverless cars, not commercial fleets.

• Cars are fully automatic, not semi-automatic.

⸻

📊 Step-by-Step Approach:

1. Population Breakdown:

• 🇺🇸 Total US Population: ~330 million

• 👨‍👩‍👧‍👦 Avg household size: 4 people

• 🏠 Estimated households: ~82.5 million

2. Income Segmentation & Affordability:

• Only high-income and upper-middle-income groups can afford luxury/driverless cars.

• 🟢 High-income (10%) → 8.25M households → avg 2 luxury cars

• 🟡 Upper-middle (20%) → 16.5M households → avg 0.5 luxury cars

• 🔴 Remaining 70% are not considered for this analysis (due to affordability).

3. Calculating Potential Users:

• High-income: 8.25M × 2 = 16.5M cars

• Upper-middle: 16.5M × 0.5 = 8.25M cars

• Total potential market size: ~24.75 million users

4. Adjustment for 2030 Trends:

• Assuming gradual adoption and replacement cycles, let’s say 40% of these buyers choose driverless cars by 2030:

• 24.75M × 40% = ~10 million users

⸻

📈 Final Estimate:

🔮 ~10 million personal-use driverless car users in the US by 2030
