Sorry Mate I Didn't See You, I Was Distracted By Your Flashing Lights.
I like that and I think my original post slightly asked for it, but my point was a serious one.
Any road user is taking in a huge quantity of signals
all the time. Many of them will modify that road user's speed, direction or other choices.
(This is being brought home to me all over again as I've recently taught my eldest to drive and am now riding a lot with her two younger brothers).
When I drive or cycle on the road, I find that some signals are distractions that I find unhelpful. Among those are flashing front bicycle lamps, headlights left on full beam, indicators left on, front fog lights used in good visibility, high-intensity rear lights used in good visibility, motorcycles with headlights shining right into my RVM, hazard lights used in a line of parked cars, giving the impression of direction indicators and many others.
OT but relevant: Some unhelpul signals are (bizarrely) design features on modern cars. Alfa and SEAT are among others to go for the recent vogue of putting rear lights in concentric rings, so indicators can blur out when braking. Also, front indicators close to main headlights can be hard to spot from some angles. I have no idea why car manufacturers do this, but we all see it every day - and often in very late models.
In the scheme of things, flashing front lights are
nowhere in terms of annoyance, but they are
'on the list' nonetheless. As I said earlier, I often use a flashing rear light when cycling as I find that helpful as a driver in pinpointing bicycles in a long stream of tail lights. If something makes sense to me as a driver observing bicycles, I adopt it. Flashing front lights make no sense to me as a driver, so I don't use them on my bicycle. This is a matter of opinion and I support fully any cyclist who thinks they do make sense.
I have absolutely no issue with the use of flashing front lights, but I choose not use them myself for the reason given.
I still think the matron in question had a bee in her bonnet about a 'nothing' issue and probably displayed poor workplace behaviour, but she is not alone in disliking flashing front lights.
