> You are not forced to have to own a car

Well, no, but

> society have built itself to be almost fully dependent on cars

You don't state where you live, but odds are good your country is mostly car dependent. Sure transit is useful for a few (10%) of people who live in the city, but if you look at the numbers in almost every country cars are the vast majority of transport if the country is rich enough to afford them. If the country isn't that rich you will see other things, but as they become richer they become car dependent.

For what it's worth, you might find this list handy the next time you find yourself in a discussion about car dependence and how it varies across the world.
