Time-Saving Bias

Time-saving bias is the human tendency to misjudge or incorrectly estimate the amount of saved or or lost time when increasing or decreasing speed. This occurs through a failure to understand the effects that consistent speeding up/slowing down will have as opposed to traveling at a consistent speed. Research has shown that when people travel at a consistent speed between a starting point and a finishing point, they generally make about the same travel time as people who are consistently speeding up, and then slowing down, etc.
