I enjoy riding bike more than driving the car. In an urban city with traffic jams it's a no-brainer.
Living in the country, it's a different matter.
My family has always had just one car, for hauling large grocery shopping, or driving someone when they're ill etc. It got about 3000 km per year for the whole family use. I've always been used to not driving a car - seeing that as a luxury to be used only when necessary.
But having a household without a single car at least can be quite limiting. If you're tempted with driving too much, get a small, cheap, ugly car you don't enjoy driving, or being even seen in for that matter.
