I think it follows from Newton's laws of motion.

It does not matter one jot in what you see as other problems with
STATS19.

We are talking about cyclist only accident figures vs pedestrian only
accident figures.

It is obvious (to those who want to see) that a cyclist is more likely
to have an accident and to suffer injury than a pedestrians is -
where not other vehicles are involved.

You have claimed that the stats data for cyclists is distorted cf
pedestrians. You have not explained why.

Feel free to explain why more cyclists should suffer cardiac arrests
than pedestrians and hence contribute to the STATS19 data when
pedestrians don't.

Perhaps you are saying that cyclists are more unhealthy - or more
likely to have cardiac problems - is that it?

Feel free to explain why there should be more people of a greater age
cycling - and hence having a heart attack - than there will be
pedestrians of same age group having heart attack.

(It is pretty obvious to me that there will be many, many older
pedestrians than there will be cyclists; but perhaps it is not obvious
to you)

2008 DfT Figures: Passenger casualty rates Per billion passenger kilometers:
Killed or seriously injured: Pedal Cyclists : 541 Pedestrians 382
All casualties: Pedal Cyclists : 3814 Pedestrians : 1666
(Pedal cyclist casualties up 9% - pedestrians up 2%: Cycling is becoming more dangerous each year when compared to walking as a means of transport)

it is at best disingenuous to posit the idea of potential damage negating
benefits if all you have is supposition and theory.

Fine. I don't really care either way. It's up to the individual to
decide what they wish to wear when cycling.
