I think, the probable reason this elderly was on the road and not the pavement: the pavement was probably too narrow, full of entitled motorists who had installed a dropped curb driveway and ruined the it, and constantly ended all the time.
That is, pretty much every UK council treat cyclists with contempt or an after though - aided by motorhead lobby and tabloids going on about a war on motorists - but who really gets the worst treatment is pedestrians. Councils continue do next to nothing for pedestrians.
Just consider a few things:
- Dual lanes roundabouts (even Spanish and Portuguese roundabout have zebra crossings) in city centres! Ever seen pensioners trying to cross near those? Even if 1 in 50 motorist stops to let them over, some speed nutter beeps them!
- Pavements which constantly break for:
- someone who had to install a driveway to the front of their house and was allowed the make the pavement there uneven. Why not insist that pavements never break and that anyone who installs a driveway has to install a big cast concrete curbstone with a 45°-60° edge which nobody would ever dare to drive more than 5 kph over?
- Why are those crazily super "open" bends into side roads, parking spaces allowed? Why not make the pavement continuous over these minor side roads and parking spaces with the above big cast concrete curbstone and have the rules of the road treat this as a zebra crossing with a speed bump? Why do car drivers think they can just pull out or in front of everyone walking?
- Even on large roads, a lot of the time a zebra crossing would barely slow down the speeding motorists driving bumper-to-bumper, but councils barely install them.
- Most pavements are far too narrow. Even brand new ones (planners haven't got a clue, don't care, or live elsewhere and always drive; or may all of that). The minimum width of pavement should be wide enough for two mobility scouter to pass each others comfortable. So about 1.5m minimum. Everything else should follow from that
- This rule should be for all urban areas: if there isn't enough space for the min 1.5m pavement, reduce the width of the road. Take away on-street parking (the cheapest land in the UK even where licensed)
- If a road is still too narrow for that, the make it one-way.
Once councils have done the above, then people whether elderly or children will start to feel safe when walking.
The wide of a vehicle should not matter, unless car drivers try to squeeze past them as the usually try to do with bicycles despite it clearly being against the rule of the road.
Difference is, only one transport user regularly kills hundreds: car (and van, lorry) motorists.
Yes, there are selfish idiots in all walks of live.
However.
- Egoistic motor vehicles drivers kill thousands per year. (And main far more, plus intimated many people from walking or cycling).
- Egoistic bicycles kill maybe one person per year.
- Egoistic pedestrian kill maybe one person once every few years.
It is easy which group needs to prioritised in terms of safety.
