Nowhere on my link does anyone recommend a general 4-second rule, and this doesn't even account for the fact that we should expect safety organizations to err on the side of too much safety. Note that your recommendation is specifically not a tailored approach designed to adjust to risky situations, but rather a fixed criteria. Your strategy to take all possible precautions regardless of large efficiency loss doesn't align with the reasonable tradeoffs that the vast majority of humans make.
