Are you suggesting that it be made illegal to walk along a country road at night? Are you suggesting that parking at night must not be allowed unless the roads are well lit. In a way you have answered your own question, if a question it is, an accident was avoided because you were driving at a speed commensurate with the prevailing conditions. The onus must always be with the driver of a moving vehicle to ensure that the route he intends to adopt is safe and this includes driving within the limitations of his eyesight, if an oncoming car dazzles him to the extent that his vision is dangerously impaired he should halt until the conditions improve!
This particular parking phenomena may be witnessed in almost every village in the County as well as virtually every minor road in the suburbs with parking taking place in all manner of unlikely locations often involving the pavement and often reducing the width of the road to such an effect that it is only possible for traffic to progress in one direction at a time! The police 'turn a blind eye' to these situations for the simple reason that there is no practical alternative!
It could be argued that issuing tickets to drivers who park in what is effectively a large field opposite the stadium contributes to the exacerbation of this situation - it is a fact that tickets would not be issued to any pikeys who decided to park on these enormous verges, quite the opposite, they could park their caravans as well for as long as they liked with no fear of being prosecuted for parking on a designated freeway! This may be related to the revenue generated by persecuting relatively law abiding people who have no option other than to pay dearly for the privilege a few hours safe parking(as opposed to weeks of parking with the accompanying desecration of the entire area for free! Most of the people who park there are completely unaware of the repercussions!
That said, pedestrians should, in the interest of self preservation, endeavour to wear something of a reflective nature to assist drivers with sight difficulties. This precaution extends to children for the same reasons.
It is a sad fact that not even motorways are well lit at night these days!
Not convinced that this subject falls into the category of technical matters.
Knowledge is strength!
