It already did. Its just that some people like to override it with their own
"ruling".
Next you'll be saying "lets get rid of traffic lights and just flash people
across at junctions"

The existing rules are tried and tested and they work. Its only when people
try to override them with their own ideas that the problems occur.

Subject to the condition that you mention - that traffic needs to decide "is
he giving way to *me*", I think there needs to be a way of positively
signalling that you intend to give way to traffic. If there was no way for
me to signal this intention from afar, and the only way was to slow down and
stop and w-a-i-t until the person decided that I really *was* giving way to
them, then it's very simple: I'd stop giving way to anyone because it would
put me to much more inconvenience and slow down the traffic behind me much
more.

The only time I've seen any ambiguity about who an "I'm giving way to
someone" headlamp flash is intended for is when traffic is approaching a
side road and there is traffic waiting to turn left or right out of it and
also traffic in the middle of the road waiting to turn into it. But usually
they are both covered by the same signal: if I give way to oncoming traffic
that is turning right across my path into the side road, traffic turning
left out of it can also go.

A cross roads is a difficult one: if I'm on the major road, am I letting out
traffic from the road on my left or the one on my right?

If it is frequently necessary at busy times to let traffic out from side
roads, otherwise it will *never* get out, that is an admission that the road
junction needs a roundabout or traffic lights.

If I want to turn right onto the main road at the end of my partner's road,
which is just at the point where a dual carriageway (on my right) becomes a
single-lane road (on my left), I could be waiting for ten minutes or more
for a gap to occur both ways simultaneously. The usual remedy is to turn
left and then do a U turn into and out of a side road on the right a couple
of hundred yards away. Even though I now only have to consider one stream of
traffic instead of two, it can still result in long delays - now with no
means of escape as the road that I do a U turn into is a cul-de-sac ;-)

I have been in situation of telling pedestrian I am giving way and
stopping (to speed things up as you say) and there's been a car
waiting to pull out which also accepted the signal as to them. So you
need to be ready to give way to all once you give the signal or if the
situation is complex, don't give it at all.

I don't see any need for a ruling. I always treat a headlamp flash as
ambiguous, and I would encourage others to do the same. I don't expect
things to change in that regard within my lifetime.

FWIW there already is a system of green lights on trucks in India, which
I think means "I can see the road ahead and it's safe to overtake me".
(Er, no thanks)
