Note: These values are hypothetical teaching numbers, not permanent game constants or recommended targets.
Baseline Setup: Suppose you have 4 occupied pads, each earning 25 green value per cycle. The Toll Level panel shows a 2x multiplier with a 2.0-second cycle timer.
Baseline Rate = (25 × 4 × 2) ÷ 2.0 = 100 cash / second (6,000 / min)
Candidate Upgrade: A candidate car costs 4,000 and has a green value of 55. It would replace your weakest pad earning 25.
Net Gain per Cycle = 55 − 25 = +30 per cycle
Added Income Rate = (30 × 2) ÷ 2.0 = +30 cash / second
Payback Duration = 4,000 ÷ 30 ≈ 133.3 seconds (2.22 minutes)
Conclusion: After 133.3 seconds of toll flow, the candidate car has fully recovered its 4,000 purchase price.
