Mrs North and I own one car between us. It’s a two seater. Last purchase payment on it is next month.
I hardly ever drive it, but do now and again, mainly at weekends when we do stuff/go places together. My personal transport is done by bike. I try to do as much as I can by bike, and a rack and panniers certainly help. I intend to turn one of my bikes into an Xtracycle for more arduous work – I also need something to transport my track bike to the Velodrome when a car isn’t available….*
Mrs North does use it daily, however, but that’s because she’s basically unwilling to travel to and from work by bus or bike. Life’s too short to argue, so I let her run it (it’s regesitered in her name), fill it with petrol etc.
Frankly, since we live in a city, there is really no need for a car for much of our life – we could both easily cycle/take public transport/walk for the majority of what we need to do. I think not owning a car and hiring one as and when is a really good idea, and is something that could suit many more people than would actually consider doing it.
*The subject of a separate thread, I suspect.
