The HC in my view is quite reasonable about this. It says (not in
exactly these words):

Make sure you leave enough room to avoid hitting the bloke in front if
he suddenly slows down or stops. If you want to be sure to be safe,
never get closer than the overall stopping distance, but in practice a
gap of 2 seconds is OK (but leave more time if wet/icy or driving
something that doesn't brake too well).

Saying "the safe rule" is the HC's way of hinting that good real-world
drivers might not always slavishly follow it.
