It seems to me like you don't actually know what this community is about and you're just mad at the somewhat intentionally provocative title. You wouldn't be the first.
We don't want to take people's cars away. We want good urban planning so that not using a car becomes a viable alternative. If done right this also improves the lifes of people who still need cars for various reasons. If you live in a rural area you'll probably always need a car and that's fine.
