My Uncle drove one of those 'powerchair' things.....get one with big wheels, it goes up and down kerbs.....and it has a forty mile round trip battery.
That was enough to take the old blighter into Glasgow and back home from where his R.C. model boat pond was....it's a long road, so he decided in his 90+ year old wisdom that he could just nip down and take a short cut using the hard shoulder of the motorway for a bit of it
I jest you not, he looked like an eight year old schoolboy who'd been caught by a teacher doing something dangerously stupid when the Polis gave him a lift back home with a flea in his ear. "It was just a couple of miles!", he said, "I wasn't hurting anyone", he said. "It saved me half an hour and cut five miles off the journey", he said.
"Don't do it again!", said the Police man who was as young as the Uncle was when he went to war.
The Uncle became the bane of their lives, because he roped in the Auntie (might have been his Granny? can't mind now, Annie) of their sergeant, and she used one of the wee chairs to nip around too...so they reported every single pavement blockage, and kerb and road problem...and since they were 'senior citizens in distress' the police had to as promptly as possible answer their call.
I bought him a High Viz padded jacket, so at least we had a fighting chance of seeing him on the road ! That workman's jacket was brilliant, it kept him warm and dry and visible even in our sodden wet and cold bit of the world. Worth buying.
