Why is a following gap often measured in seconds rather than one fixed distance in metres?
Correct answer: A time gap corresponds to more physical space as speed increases.
Why
Choose a fixed roadside reference. After the vehicle ahead passes it, count the time until you reach it. The same number of seconds represents a greater distance at a higher speed. Adjust the gap for conditions; this lesson does not set one universal interval for all roads or weather.
