Following distance is not about meeting a minimum to avoid fines; it is a safety buffer that gives you time and space to react. K53 guidance recommends at least 2–3 seconds, more in adverse conditions. Treating it as a buffer means increasing it when tired, in rain, behind large vehicles or when visibility is poor. It also means not letting others tailgate you into reducing your own gap. This mindset shifts following distance from “what is the least I can do?” to “what gives me enough margin for error?”. That margin saves lives.
