The bizarre thing is that on a cycling website, people are still struggling to see the utterly obvious answer.
No-one is suggesting for a minute that *everyone* suddenly ditches their car and starts making their way around on a bicycle. Even in places that embrace cycle commuting as a way of life don't do this.
The point is that the more people who cycle, the more good cycle infrastructure we build, the more we make bikes be the priority, the better things get *for everyone*.
You need to get around in your van with tools, it'll way better because there's less cars and the bikes are over there, out of the way.
You need to move house, no problem. You can use a lorry to do it (although plenty of people in cycle-orientated cities move house on their bikes).
Are you disabled? No problem, you can get around by car.
Lazy? Still no problem, you can get around by car and it will be much better because there's not so many cars.
It works. Those places that make these changes can show that very, very clearly it works, and really quickly too. It saves money, it makes things better for PEOPLE and it absolutely is the right thing to do. What's immensely frustrating is trying to get everyone to see this.
