No, you want a world without cars. That is your stated goal. You backtracking is you trying to take a more neutral position than your original one, which is "cars bad, everyone walk/use public transportation". That's ableist, hateful, and impractical for a ton of people, including people who don't have mobility issues for so many damn reasons, including transporting goods, weather, going places as a family, having a shelter for not only the weather but for anything else, and going directly to and from one's destination. Cars are the primary way of transport and nothing you and your anti-car buddies say are going to change it. You're like vegans and religious people arguing against common sense and logic and reason; you are contrarian for the sake of being contrarian.

Wake up and accept modern life and our necessities.

Fuck "fuck cars". There's your "unproductive language", which is, you know, just language. Being vulgar isn't unproductive, it has its reasons to exist. Which, in this case, to in no certain terms damn your entire worldview.
