IIRC the law is that a pedestrian *always* has right of way on public
roads.

Of course.

Pedestrians have an absolute right to travel on the Queen's highway.
Just as horses and cyclists do.

Motorised vehicles are only permitted to drive on the highway if
properly taxed and licensed to do so and when conducted by a person
suitably trained to abide by the license.


Just as "Steam gives way to Sail" afloat.

But just try challenging a tanker in your sailing dinghy. Or
wandering across a dual carriageway in front of a heavy lorry.
You'll find your "right to use the highway" won't count for much in
court :-)
