Car Dependant Infrastructure in the United States and Canada are awful for CO2 emissions, and are SUPER classist. It is often necessary to use a vehicle to get anywhere in North America, and because bicycling is extremely dangerous, and public transport infrastructure has been completely gutted basically everywhere, the only way to consistently and safely get anywhere is with a car, which is extremely expensive. There is also a classist social stigma behind public transport, where if you aren’t in a car, you must be one of the poors. Our road systems are awful, too. I don’t have any real protection biking to school, besides some painted lines, and it’s almost impossible to get anywhere outside of a vehicle (and urban California is relatively utopian), and going to stores to get food and other essentials is awful and unsafe outside a vehicle, so poor people just have to go through hell to get essentials. Everything about North American stroads (an awful mix of roads and streets, which accomplishes the purpose of neither) is built to hurt anyone outside of cars, and cars hurt the environment and people outside of cars, and car-dependance hurts social connection and community buiding (because you need to go through driving a car to interact with people, and it’s unlikely you live close enough to someone to not drive to them, because houses are so far apart because of suburbanization, and because nobody is able to intact outside because everywhere is ugly and unpleasant, because of cars and stroads), anyone outside a car, and the environment again, because parking lots take up space and it’ll take a ton of time and destructive work to fix that in the future!
