So maybe nobody has told you this befroe, but there's a certain stage in human society where it's become clear that cars are a primary cause of global warming, obesity, and loneliness. Being unable to recognize that cars are a societal ill starts to reflect poorly on people, regardless of what their argument is.
Now, maybe you haven't made that realization (it took me losing my best friend to a distracted driver to understand), but perhaps it's something to consider. Agree or disagree to the topic, it's all good. But every day that we continue to prioritize car infrastructure, more people die needlessly.
