Cast_Iron deftly scribbled:

Consider the predicament of people walking alongside both a road and a
railway.

Is this a sensible method of ensurring the safety of the people of
this country?

What other 'sensible method' would you employ ?

If these 'people' took sufficient or due care and attention then they are
sufficiently likely to walk alongside a roadway or railway in a degree of
safety and with a high probability of finishing their walk or journey.
Very, very few people actually go out with the intention to crash or be
involved in an 'accident'.

Your viewpoint appears to disregard convenience.
