Perhaps, but enough to make it worth doing something?

Much as any engineer tends to view the world as a sub optimal
implementation that needs to be fixed, there comes a point where you
need to choose a problem big enough to make it worth spending the effort
fixing it.



Like fixing the fences next to the railways rather than spending it on
automatic train controls to stop the odd crash.

Fixing the fences is the engineering choice to lower the death rate on
railways, ATC is the political solution to lowering the death rate on
railways.

I reckon the death rate of people getting through fences to access the
rails is in the noise compared with the incidents on crossings and the
like.

Fencing railways is to keep the railway in and not the public out ! its
on an old bit of rail legislation from 1800 odd!...
