With that in mind it would seem that legally there is nothing to
prevent cyclists from bunch riding, which makes a lot of sense as
bunch riding seems to make much better use of the road.

That's the problem with words like safe, too open to interpretation.
One man's safe and reasonable thing to do is another man's insanity. In
bunch riding I would expect that the riders are (generally) informed
about the potential risks and potential benefits and make a judgment
accordingly. Being a slow coach commuter, I have no idea.

Doing some rough maths, 30Km/h equates to a little over 8M/s. Three
second gap would require a 25M gap between two cyclists riding at
30Km/h.
I do leave a good gap between me and another cyclist because I have zero
experience and / or skills in drafting, I'm pretty sure I don't leave a
25M gap though, more like a ten meter gap. Thus far that's proved more
than adequate.
Traveling at 60 km/h a 50M gap is required for the 3 seconds thing.

Apples and pears, I'm talking about how much of the road is used per
user. It is much easier for a car to overtake a bunch of ten cyclists
in one go than it is to overtake ten individual cyclists one after the
other. Overtaking maneuvers are inherently risky so reducing the number
of times a car has to overtake can only be a good thing.
I pointed this out to my wife the other day when we overtook a bunch of
fifty going down North Road. Her comment was that they should be in
single file, I explained that how they were riding was in fact a good
deal safer than riding in single file as it forces other road users to
overtake properly. I'd have had a harder time making that argument if
they were strung out over 625M rather than the 30M they were using. Or
in the case of single file, 1.25Km rather than 60M.
