The Linear Bias – NeuroLogica Blog
So in any operation, whether driving on a journey, completing a task at work, or maximizing the efficiency of a factory, it is best to focus on the slowest components. There is significantly diminishing returns when improving already fast processes, and they are probably not worth it.
While driving, for example, speeding does not make sense from a risk-benefit consideration. Speeding means you are going over the speed limit, which is already reasonably fast, so that time saving is actually negligible. Going from 60 to 80 mph on a 10 mile commute would save you 2.5 minutes, and increasing further to 90 mph saves you a further 54 seconds. For that you are risking a costly and time-consuming ticket, burning more gas, and risking an accident.
