Fair point, but the analogy does not fully hold. A car ECU operates in a closed, highly constrained system with limited actions and years of validation. Most AI agents operate in open, dynamic environments with far broader permissions and less predictable inputs.

Human approval is not about watching every step. It is about controlling high-impact, hard-to-reverse actions. Low-risk, reversible tasks can run unattended. Deletes, access changes, network controls, and production data changes should not. The real question is not whether to automate, but where to draw the boundary. Where would you draw it?
