Yes, I am.

And are you a health care worker who is aware that there's no shortage
of people who are killed every year from trips and falls? If you are,
you'll hopefully realise that any arguments you make about cycle helmets
/should/ apply to walking as well, especially where descending stairs is
involved, since falls doing that are (a) similarly able to fubar the
nervous system and (b) that's the sort of incident that cycle helmets
are specified to work in (i.e., a fall from saddle height while
travelling at low speed).

But
perhaps we should ensure that the risks of not wearing helmets are well
known?

We certainly should. However, that level is basically a zero reduction
in /serious/ head injuries, according to the most reliable information
we have from population level data sets, which is probably rather less
effect than most people think.

Cycle helmets will save you from a nasty bump and a graze if you're in a
basically non life threatening accident not involving motor vehicles
where you happen to hit your head. Outside of icy days or doing
technical of-road, that sort of thing doesn't happen much, and if it
does it's very unlikely to kill you.

I'd like to think not!

Doesn't mean you're not unaware of the true effectiveness of cycle
helmets, however. Start reading at www.cyclehelmets.org and get Clued Up...

I think all bicycle riders should wear helmets.

I probably should have worn one on the Rural South 300 on Saturday. At
70kph on a narrow twisty descent my Tchibo headscarf blew off and I had
to stop and go back for it. A helmet would have prevented this. One
rider did fall and cut his head. As he got up to finish 1.5 hours
before the next rider home it seems as though it was the sort of minor
injury that might well have been avoided if he'd been wearing a helmet.

Cycling helmet won't help at that speed, maybe bicyclists should wear helmets and keep below 15mph.

A gross simplification, indicating you haven't really thought about.
The speed the lids are designed for is a full on impact, but a glancing
blow, such as you'd have hitting the road at an angle at 40 mph, is
likely not to destroy the lid, and more to the point likely to save you
a very nasty graze. Which is what can reasonably be expected of lids,
rather than saving your life.

If the lid is polycarb skinned then at 40mph it will, in all likelyhood stick to the road and allow the neck to twist, ouch.

I was just being ironic, I know it is hard to understand, but this subject gets done to death every couple of months, I encourage my kids to wear helmets, but realise that once they get faster and head out on the roads the helmets will not save them, experience might, I sometimes wear a helmet even though I ride a recumbent trike, my average speed is significantly higher than that which bicycle helmets were designed for but it is very difficult to tip a tadpole trike so I am less likely than most to hit my head on the road.

It would be more likely in most circumstances since the helmet will deform (as
intended to absorb some of the impact force), but will then be more likely to
have good frictional contact with the road (which an in-tact rounded head
wouldn't).

It's swings and roundabouts.

If you knew exactly which type of accident you were going to have (and how
fast), you'd be well placed to decide whether or not to wear a helmet.

Not that that's much help.

But it's in exactly that sort of impact that rotational injury occurs,
and is why wearing a helmet may well be more dangerous than not. If I
was going to strike the road a glancing blow at 40+mph, I would very
much rather not be wearing a helmet, because I believe on the basis of
the evidence available to me that my chances of survival as a thinking
person would be very greatly lowered.
