We're both working, and went down to 1 car within a year of moving to our current house, about 6 years ago. It was very obvious that we only needed one car (there was still some apprehension at first). There was always a car in the drive way, we were switching cars to keep them both moving - not because both were needed. But, we were already big users of public transport and live on good transport links, 10 min walk to butchers, Fruit and veg shop, other shops, supermarket/hardware/etc. a 15 min walk.
We'd need to both change jobs to need a car for us to re-consider - I'd rather earn less than deal with hassle, but who knows what future holds and what will motive future me. My OH works from home, but didn't when we dropped to one car.
I walk more with one car, it takes me a bit longer to get to certain places, but I get a bit of movement in. During Covid, I used the car a lot more and had joint problems walking enough - walking/public transport fixes that without trying.
