How often is your wife's car used for household errands? I don't own a car but occasionally I've borrowed one for certain things.

It's cheaper to buy bulky packages of say rice or toilet paper, but they're inconvenient to move without a car. Furniture is nearly impossible to move with the bike I have. I could get a cargo bike, but where I live that would be impractical without a garage or a big shed to store it, whereas a car can just sit in a driveway.

I think I'll be able to get by without a car for the foreseeable future, but I'll probably end up using cars occasionally. If I can't borrow one, I'll maybe start using a car sharing service.

I'd use public transit, but honestly where I live and where I want to go it's only slightly faster than walking, and so it's almost never a worthwhile option.
