with your argument.
Irellevent, deaths per passanger mile are a much more useful metric.
It is but one way of looking at the figures, but there are others.
Each of these ways may tell a different story. Which forms of
statistics are chosen to be trumpeted (and which are ignored) by
official bodies tells us something about those bodies.
For example from the viewpoint of a pedestrian, the number of km
travelled by the one causing injury is largely irrelevant. What
matters is the danger they cause to the pedestrian.
What is the safest form of road transport? A lorry, people in the
lorry often survive because of the heavy construction. What is the
most dangerous form of road transport? A lorry, their heavy
construction often causes the death of people outside the lorry. It
is all a matter of whether one looks at safety from the point of
view of those doing the travelling, or those affected by it.
Quoted message said:Air is by far the safest.
Measured in certain ways, see my first paragraph.
The official figures are also comparing apples with oranges. Nobody
pops out to the corner shop to buy a newspaper by aeroplane.
