What this topic is really about

The three-second rule gives you time to perceive a hazard and react before reaching the point where the car ahead was. Pick a fixed object the lead car passes and count; if you reach it in under three seconds, you are too close. In rain, fog, or at night, extend the gap to four seconds or more.
