Many people literally die each year because of car-centric infrastructure, and you’re basically telling us to calm down? No fucking way.
Before cars, there used to be a massive amount of infrastructure for trains and streetcars, not to mention walkable neighbourhood, but they all get demolished for cars. So yes, we do operate like that.
And did I mention that car-centricity kills people each year? So yes, eliminate all cars if we have to. But honestly, I don’t think anyone wants to eliminate all cars, just those we don’t need (which is most of them).
