Owning a car is expensive, at my vacation home I do not have a car. Going to town (2 miles) walk or ride with a neighbor 3-4 times a week to do business, buy groceries, have a couple of beers. Taxi back home at $5 x 20 trips is $100 a month, pay no gas, no registration, no insurance and never bought a car.
Some people enjoy going for a drive - it’s not always just getting from A to B. Older folks especially, who can pass the test often see driving themselves as proof of their independence.
I'm currently at our winter home and there's no way we could get by with even one vehicle, let alone no vehicle. We each need our own vehicle at all times. There's just too much going on to try and survive without two vehicles.
