liney's right, drivers are constrained by car parks. Where we live, all the streets are permit parking and crowded. We do have a car, but people who drive a lot tend to get flustered at the idea. My dad, for example, panics at the idea he might not be able to park in a comfortable three-car-sized space right outside my house, and will not take the park and ride, park in the car parks two, ten, or fifteen minutes away, or even let me park is car (which I can do without needing a space the size of a football pitch).
We do have a car, but I rarely use it for the things suggested.
IKEA - you go, you look, you get them to deliver (obviously).
Compost - delivery, or I get cheapie ones from Poundland which is at the end of my street. I can lug that amount of compost a few hundred yards and it's probably good for me. DP and I can, easily.
Floor sander - we rent. There may be a correlation between renting and not shelling out on cars, obviously.
Big shop - order it, or bus with a shopping trolley, like your nan.
You have me with the rural pubs (which is partly why a car is nice) but it's not necessary. You might as well observe that, in said rural pub, drivers are constrained to a half pint whereas those of us who have to get a taxi can at least try the beer properly.
As to rain - really?! You dissolve?
