Residential street, outskirts of London.
No parking restrictions but also not all houses have driveways (or driveways big enough for all cars in household) so there is still an element of demand for on street parking, which is limited because due to width of road, need to allow other vehicles to pass through etc people can only park on one side, not both.
about 5 doors down lives an elderly lady (at a guess in her 80s). Her DH died a few years ago now - he was a bit of a tinkerer with 'vintage' cars, and usually had 2-3 in various states of disrepair at any one time. SInce he died, there's been 2 shells of cars - think no wheels, missing doors etc on their drive under tarps, and another one that looks physically intact on the road.
Obviously it's completely up to her what she does with the cars on her drive, but the one on the road is a really big old car, 50+ years old, you could fit 2 small modern cars like a Fiat 500 or similar in it's space. According to the Gov.uk website it's MOT ran out in 2017, and I'm pretty sure it hasn't moved since then - there are weeds growing round it. It does seem to be taxed but I guess that's just a formality given it's age. It doesn't seem to be a runner, and whilst I could understand them maybe wanting to keep it for sentimental reasons or a family member, but I'm not sure it's fair to keep it on the street occupying effectively 2 parking spaces indefinitely.
I'm not unsympathetic, and I certainly wouldn't complain if all the cars were on her driveway, but taking up a road space (or two) essentially permanently just seems a little unfair - or is that me?
