Owning a car if you need one is not in itself a problem. “fuckcars” isn’t about blindly hating cars, it’s about being aware that cars are inefficient, dangerous, and bad for people’s health. It’s about raising awareness about how car-centric and car-dependent society has become, despite there being better ways to structure transportation.
We’re not some kind of cult setting rules for how people should live. If you need a car, buy a car, if you want to own some kind of ridiculous lifted truck, you can do that, but I’ll reserve the right to make fun of you and think you’re an asshole.
