Your idea is a pie in the sky that will never be achieved.

I'm sorry, I didn't see the sign about "dreaming not allowed".

Ofcourse it is possible to live without cars. Most of human history people has been fine without cars. It's just the past hundrer years it has been normalized by the machine through advertisements and capitalism.

Car infrastructures require over-production, so if we want cars, then we have to accept that we can't live with nature. Seems like you chose the game over screen.

The supposed reason we need cars is to drive to work, go to grocery stores, visit friends from far away. But there is nothing saying that life has to be this way, we don't need to reach the world. It should be sufficient to live slowly and in our local communities.
